Who should be responsible for precipitation change, natural variation or human activities? — Characteristics of precipitation in South China and its surrounding area as viewed by TRMM PR and MODIS

Theoretically, precipitation is regarded as the result of synthetic interaction between atmospheric thermodynamic processes and geographic environment factors, and is considered as one of the proxies for climate change. The spatiotemporal distribution of precipitation in turn will impact on atmospheric thermodynamic processes and lead to changes of other atmospheric parameters, i.e. the feedback process on climate. Therefore, investigating global or regional precipitation variations is important for understanding climate change.
