Analysis and Simulation of Relation of the Weakening Trend of Land-Sea Difference of Springtime Mean Surface Air Temperature in South China and Its Ambient Ocean and Intensity of East Asian Summer Monsoon
|
Abstract:
Using NCEP/NCAR reanalysis data,the linear change rate(LCR) of springtimemean surface air temperature(SAT) is calculated.It is found that the negative LCR is dominant in South China,but the positiveLCR is mainly located on the ocean,i.e.,there exists a weakening trend of land-sea difference of springtime mean SAT in South China and its ambient ocean.The composed analysis result shows that this weakening land-sea difference of SAT is correlated with the weakened trend of summertime southerly in East Asia.Acc...
