Based on the observation and NCAR/NCEP reanalysis data, the advection term and perpendicular term of local temperature variation are estimated, and the non-adiabatic term is estimated too. The advection term varies with comparative complication, but its role is very weak. The perpendicular term leads to increase 1%—5%. The local temperature increment in Anhui is mainly from non-adiabatic term, and it takes significant role in local temperature increment.
