Mesoscale convective complexes (MCC) systems produce a wide variety of severe convective weather such as heavy rainfall. The MCC is a subclass of mesoscale convective systems (MCSs) defining as a convective cloud system that is large, long lived, and exhibits a quasi-circular cloud shield. This study evaluates spatial distributions of heavy rainfall over Java Sea region during wet season conditions; namely, December January February (DJF). Rainfall data set obtained from Tropical Rainfall Measuring Mission (TRMM) measurements for period 1998 - 2013. Heavy rainfall is represented by amount of maximum rainfall. Diurnal cycles of rainfall features present that the development and movement of convective rainfall is mainly related to the land and sea breezes. The evolution of hourly rainfall at 3 hourly intervals, illustrates a clear diurnal variation over Java Sea region. From 22 Local Time (LT) to 10 LT the large average rainfall mainly located in the Java Sea. Then from 13 LT to 19 LT the large average rainfall mainly located in the inland. While from 10 LT to 13 LT the large average rainfall located in both the Java Sea and the inland. And from 19 LT to 22 LT the large average rainfall located in Java coastwise. This situation has agreement with the formation of its maximum and standard deviation in diurnal cycles. The daily convective rainfall in the inland region is much more than that in the sea region, but heavy rainfall is often found over the sea.
