Diabatic heating data from NCEP (1 and 2) and ERA40 are compared to analyze the applicability of these data in the Asian region

particularly in the Tibet Plateau(TP) and tropical Asia. In spite of slight difference in vertical integration of total diabatic heating rates from three data sets

the spatial distribution shows good agreement. Seasonal and interannual variability of the mean diabatic heating over TP shows agreement in the magnitude and trend. Particularly

the correlation coefficients of interannual variability of the mean sensible heat flux over TP among three data sets exceed 99% or even 999% confidence level. Therefore

the reanalysis diabatic heating data over Asia

even over TP area

are feasible to a certain extent.
