The Weather and Climate
The climate in Southeast Asia is mainly tropical-hot and humid all year round with plentiful rainfall. Northern Vietnam and the mountainous parts of Laos and Myanmar are the only regions in Southeast Asia that feature a subtropical climate, which has a cooler winter with potential snow.
The majority of Southeast Asia has a wet and dry season caused by seasonal shifts in winds or monsoon. The tropical rain belt causes additional rainfall during the monsoon season. The rainforest is the second largest on Earth.
An exception to this type of climate and vegetation is the mountain areas in the northern region, where high altitudes lead to milder temperatures and drier landscape. Other parts fall out of this climate because they are hot.
Southeast Asia is one of the most vulnerable regions to climate change in the world. Climate change will have a big effect on agriculture in Southeast Asia such as irrigation systems will be affected by changes in rainfall and runoff, and subsequently, water quality and supply.
