The meteorological indicators include temperature, precipitation, humidity, and wind speed. Step 102: For each day within a preset historical time period, determine the historical normalized temperature index for each hour of the day based on the historical meteorological index for that day. Step 103: For the target time period and the future time period that is far from the target time period, determine the predicted normalized temperature index for each hour of the day based on the predicted meteorological index for each hour of the day. The processor can acquire historical meteorological indicators for each day within a preset historical time period relative to the target time period, predicted meteorological indicators for the target time period, and predicted meteorological indicators for a preset future time period relative to the target time period. These meteorological indicators may include temperature, precipitation, humidity, and wind speed. For each day within the preset historical time period, the processor can determine the historical normalized temperature index for each hour based on the historical meteorological indicators for that day. Similarly, for the target time period and the preset future time period relative to the target time period, the processor can determine the predicted normalized temperature index for each hour based on the predicted meteorological indicators for that day. For example, assuming the processor sets the preset historical time period to the past 5 days and sets the target time period to today, the processor can acquire the historical meteorological indicators for each day of the past 5 days, today's predicted meteorological indicators, and the predicted meteorological indicators for the preset future time period relative to the target time period. For instance, assuming today (the target time period) is day D, and the preset future time period relative to the target time period is the first day of the future, the processor can acquire the historical meteorological indicators for each day from day D-5 to day D-1, and the predicted meteorological indicators for day D and day D+1. For days D-5 to D-1, the processor can determine the historical normalized temperature index for each hour based on the historical meteorological index for each hour. For days D and D+1, the processor can determine the predicted normalized temperature index for each hour based on the predicted meteorological index for each hour.

This allows the processor to determine the maximum and minimum historical comprehensive temperature indices for each day. Then, based on the maximum and minimum historical comprehensive temperature indices for each day, the hourly historical comprehensive temperature indices, and formula (2), the processor can determine the normalized historical temperature index for each hour of the day. For example, for each day from day D-5 to day D-1, the processor can determine the hourly historical comprehensive temperature index for each day using formula (1). Taking day D-5 as an example, the processor can determine the historical comprehensive temperature index for each hour of that day. This allows the processor to determine the maximum and minimum historical comprehensive temperature indices for day D-5. Based on the maximum and minimum historical comprehensive temperature indices for day D-5, and the hourly historical comprehensive temperature, the processor can determine the normalized historical temperature index for each hour of day D-5 using formula (2).
[0047] In one embodiment, for a target time period and a future time period preset from the target time period, the predicted normalized temperature index for each hour of the day is determined based on the predicted meteorological indicators for each hour of the day, including: for a target time period and a future time period preset from the target time period, the predicted comprehensive temperature index for each hour of the day is determined by formula (1) based on the predicted meteorological indicators for each hour of the day: Formula (1)
[0048] Where i represents the target time period or the number of days until the target time period is preset in the future, and j represents the hour of the day, j=1,2,3……23,24.

[0051] The processor presets future time periods for the target time period and the distance from the target time period. The processor can determine the predicted comprehensive temperature index for each hour of the day based on the predicted meteorological index for each hour of the day using formula (1), thereby determining the maximum and minimum predicted comprehensive temperature index for each day. Then, based on the maximum and minimum predicted comprehensive temperature index for each day, the predicted comprehensive temperature index for each hour of the day, and formula (2), the predicted normalized temperature index for each hour of the day is determined. For example, for day D and day D+1, the predicted comprehensive temperature index for each hour of the day can be determined using formula (1). Taking day D as an example, the processor can determine the predicted comprehensive temperature index for each hour of that day, thereby determining the maximum and minimum predicted comprehensive temperature index for day D. Based on the maximum and minimum predicted comprehensive temperature index for day D and the predicted comprehensive temperature for each hour of day D, the predicted normalized temperature index for each hour of day D is determined using formula (2).

[0053] The processor, for each day within a preset historical time period, a target time period, and a preset future time period relative to the target time period, can determine the meteorological index coefficients for that day based on historical meteorological indicators, predicted meteorological indicators, historical normalized temperature indicators, or predicted normalized temperature indicators. For example, for days D-5 to D-1 in the past, the processor can determine the meteorological index coefficients for each day based on historical meteorological indicators and / or historical normalized temperature indicators. For day D (the target time period, assumed to be today) and day D+1 (a preset future time period relative to the target time period, assumed to be the first day in the future), the processor can determine the meteorological index coefficients for that day based on predicted meteorological indicators and / or predicted normalized temperature indicators.
[0054] In one embodiment, the meteorological index coefficients include a high temperature coefficient, a precipitation coefficient, and a temperature continuity coefficient. For each day within a preset historical time period, a target time period, and a preset future time period from the target time period, the meteorological index coefficients for that day are determined based on the day's historical meteorological indicators, predicted meteorological indicators, historical normalized temperature indicators, or predicted normalized temperature indicators. For each day within the preset historical time period, the target time period, and the preset future time period from the target time period, the high temperature coefficient for that day is determined according to formula (3). :

[0056] Where k is the day number, and j is the hour number of the day, j=1,2,3……23,24. This represents the historical or predicted temperature value for the j-th hour of day k.
[0057] For each day within the preset historical time period, the target time period, and the preset future time period from the target time period, the precipitation coefficient for that day is determined according to formula (4). :
[0058] Formula (4)
[0059] Where k is the day number, and j is the hour number of the day, j=1,2,3……23,24. This represents the historical or predicted precipitation for the j-th hour on day k.
[0060] For each day within the preset historical time period, the target time period, and the preset future time period from the target time period, the temperature continuity coefficient for that day is determined according to formula (5). :
[0061] Formula (5)
[0062] Where k is the day number, and j is the hour number of the day, j=1,2,3……23,24. This refers to the historical or predicted normalized temperature index for the k-th hour.
[0063] Meteorological index coefficients can include high temperature coefficient, precipitation coefficient, and temperature continuity coefficient. For each day within a preset historical time period, the processor can determine the high temperature coefficient of the day based on the historical temperature value of each hour of the day using formula (3). For a target time period and a future time period preset from the target time period, the processor can determine the high temperature coefficient of the day based on the predicted temperature value of each hour of the day using formula (3). For each day within a preset historical time period, the processor can determine the precipitation coefficient of the day based on the historical precipitation of each hour of the day using formula (4). For a target time period and a future time period preset from the target time period, the processor can determine the precipitation coefficient of the day based on the predicted precipitation of each hour of the day using formula (4). For each day within a preset historical time period, the processor can determine the temperature continuity coefficient of the day based on the historical normalized temperature index of each hour of the day using formula (5). For a target time period and a future time period preset from the target time period, the processor can determine the temperature continuity coefficient of the day based on the predicted normalized temperature index of each hour of the day using formula (5).
[0064] Step 105: Determine the cumulative meteorological coefficient for the preset future time period based on the meteorological index coefficients for each day within the preset historical time period, the target time period, and the preset future time period from the target time period.
[0065] After determining the meteorological index coefficients for each day within the preset historical time period, the target time period, and the preset future time period from the target time period, the processor can determine the cumulative meteorological coefficient for the preset future time period from the target time period based on the meteorological index coefficients for each day within the preset historical time period, the target time period, and the preset future time period from the target time period.
[0066] In one embodiment, the method further includes: determining the comprehensive temperature coefficient of the day based on the high temperature coefficient, precipitation coefficient, and temperature continuity coefficient of the day using formula (6), for each day within a preset historical time period, the target time period, and the future time period from the target time period. :

[0069] For each day within the preset historical time period, the target time period, and the preset future time period from the target time period, after determining the daily high temperature coefficient, precipitation coefficient, and temperature continuity coefficient, the processor can determine the daily comprehensive temperature coefficient using formula (6).
[0070] In one embodiment, determining the cumulative meteorological coefficient for the preset future time period based on the meteorological index coefficients of each day within the preset historical time period, the target time period, and the preset future time period from the target time period includes: determining the cumulative meteorological coefficient for the preset future time period from the target time period using formula (7) based on the meteorological index coefficients of each day within the preset historical time period, the target time period, and the preset future time period from the target time period. :

[0072] Where D1 is the day furthest from the target time period within the preset historical time period, and D2 is the number of other days besides the day furthest from the target time period within the preset historical time period. Let be the comprehensive temperature coefficient for day k.
[0073] For the day furthest from the target time period within the preset historical time period, the processor can determine the cumulative coefficient for that day based on the comprehensive temperature coefficient of that day. For each day within the preset historical time period, the target time period, and the number of days in the preset future time period from the target time period other than the day furthest from the target time period within the preset historical time period, the processor can determine the cumulative meteorological coefficient for that day based on the comprehensive temperature coefficient of that day and the cumulative meteorological coefficient of the previous day, thereby determining the cumulative meteorological coefficient for the preset future time period from the target time period. For example, assuming that the current day is day D, and the preset historical time period is from day D-1 to day D-5, then for the cumulative meteorological coefficient of day D-5, the processor can determine the cumulative meteorological coefficient based on the comprehensive temperature coefficient of day D-5 using formula (7). Determine the cumulative meteorological coefficient for day D-5. For day D-4, the processor can use formula (7) based on the comprehensive temperature coefficient for day D-4 and the cumulative meteorological coefficient for day D-5. The cumulative meteorological coefficient for day D-4 is determined. Similarly, for days D-1 to D-4, day D, and day D+1, the processor can determine the cumulative meteorological coefficient for the day based on the cumulative meteorological coefficient of the previous day and the comprehensive temperature coefficient of the day, until the cumulative meteorological coefficient for day D+1 (i.e., the future time period from the target time period) is determined.
[0074] Step 106: Determine the meteorological indicators under the temperature accumulation effect for the preset future time period from the target time period based on the meteorological cumulative coefficient and the predicted comprehensive temperature index for the preset future time period from the target time period.
[0075] After determining the meteorological cumulative coefficient for the future time period from the target time period based on the meteorological index coefficients for each day within the preset historical time period, the target time period, and the future time period from the target time period, the processor can determine the meteorological index under the temperature cumulative effect for the future time period from the target time period based on the meteorological cumulative coefficient and the predicted comprehensive temperature index for the future time period from the target time period.
[0076] In one embodiment, determining the cumulative meteorological coefficient for the preset future time period based on the meteorological index coefficients of each day within the preset historical time period, the target time period, and the preset future time period from the target time period includes: determining the cumulative meteorological coefficient for the preset future time period from the target time period using formula (7) based on the meteorological index coefficients of each day within the preset historical time period, the target time period, and the preset future time period from the target time period. :
[0077] Formula (8)
[0078] Where j is the time of the day, j=1,2,3……23,24, Preset the cumulative meteorological coefficient for future time periods to be relative to the target time period. A comprehensive temperature index is preset for the j-th hour of the future time period, which is far from the target time period.
[0079] The processor can determine the meteorological index under the cumulative temperature effect for each hour within the preset future time period, based on the meteorological cumulative coefficient for the preset future time period and the predicted comprehensive temperature index for each hour within the preset future time period.
[0080] In one embodiment, a processor is provided, configured to perform any of the foregoing methods for determining meteorological indicators under the cumulative effect of temperature.
