This invention discloses a method and
system for differentiating
typhoon impacts based on
seawater CO2
partial pressure data. The method includes: acquiring marine situation
monitoring data during
typhoon passage in the target sea area through a multi-source observation platform, constructing a standardized dataset and a climatological background field; using the
DBSCAN clustering
algorithm to segment water masses, and combining the Man-Whitney U test and
correlation analysis to determine the distribution of characteristic
typhoon water masses; calculating the
seawater CO2
partial pressure anomaly
field based on the climatological background field, constructing a typhoon
impact index
time series, identifying the core
impact area, and generating typhoon
impact trace paths; subsequently reconstructing
seawater CO2
partial pressure grid points, and constructing a spatial map of typhoon impacts; finally, analyzing the spatiotemporal changes in air-sea CO2 flux, assessing
carbon sink stability, and generating a typhoon-
carbon sink sensitivity
zoning map. Using seawater CO2 partial pressure as the core indicator, this method overcomes the limitations of traditional methods and provides reliable
technical support for assessing the marine environmental impact of typhoons.
