Inter‐decadal change of the middle‐upper tropospheric land–sea thermal contrast in the late 1990s and the associated Northern Hemisphere hydroclimate

Although the middle‐upper tropospheric land–sea thermal contrasts play very important roles in modifying global monsoon, the inter‐decadal influences of the middle‐upper tropospheric land–sea thermal contrasts in the Northern Hemisphere on the global monsoon have not investigated specifically. In this study, it is found that the summer middle‐upper tropospheric zonal land–sea thermal contrast in the Eurasia–Pacific region changed from weak...
