摘要: AbstractThe possibility of using remote sensing retrievals to estimate apparent water vapor sinks and heat sources is explored. The are estimated from a combination sensing, specific humidity, temperature the Atmospheric Infrared Sounder/Advanced Microwave Sounding Unit (AIRS) wind fields National Aeronautics Space Administration (NASA)’s Goddard Flight Center (GSFC)’s Modern Era Retrospective-Analysis for Research Applications (MERRA). intraseasonal oscillation (ISO) Indian summer monsoon used as test bed evaluate sink source. ISO-related northward movement column-integrated matches that precipitation observed by Tropical Rainfall Measuring Mission (TRMM) minus MERRA surface evaporation, although amplitude variation underestimated 50%. diagnosed budgets associated with convec...
