Supra-annual reproductive synchronization among trees in various families in Southeast-Asian dipterocarp forests is known as general flowering (GF) and sometimes occurs over region. Climatic factors like rainfall and low temperature have been proposed as triggers of GF, but lack of extensive datasets limits the validation of the proposed triggers. This study examined the correlation between climatic conditions measured with two satellite sensors, Tropical Rainfall Measuring Mission and Moderate-resolution Imaging Spectroradiometer, and flowering status at 83 forests during 2001-2010 in peninsular Malaysia. We detected prolonged drought period only before large-scale GF events. However,the triggering climatic conditions could be different among GF events. Of the four large-scale GF events found,GF magnitude was greater at forests with lower rainfall in three events and lower temperature in one separate event. The partial climatic triggers might be the resultant of geographical variations of the forest. We emphasized how remote sensing technique can be used to provide insights into how geographical condition can affect GF climatic triggers.
