Embodiment Construction
[0022] The technical solution of the present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.
[0023] This specific embodiment discloses a weighted average temperature calculation method suitable for low-latitude regions in China, including the following steps:
[0024] S1: Construct a weighted average temperature ITm model suitable for low-latitude regions in China, and the expression form of the ITm model is IT m =a 0 +a 1 T s +a 2 φ+a 3 h, IT m is the weighted average temperature, T s is the surface temperature, φ is the latitude of the station, h is the elevation of the station, a 0 、a 1 、a 2 and a 3 is the coefficient of ITm model;
[0025] S2: Using the air sounding meteorological data at the station to calculate the approximate true value T of the weighted average temperature at the station m ;
[0026]
[0027] In formula (1), e i The average water vapor pressure of the i-th layer of th...
