Correlation of Solar Cosmic Ray with Clouds Coverage in Indonesia

We study the correlation of solar cosmic ray to the clouds coverage over Indonesian archipelago. We divided the archipelago into 9 regions in longitude and 6 regions in latitude that can be represented into mostly ocean and mostly land. It is found that east part of Indonesia and mostly ocean region have higher correlation with solar cosmic ray. The model shows that the effect of cosmic ray may cause heating for triggering cloud formation.
