Floods


After several posts which talked about tropical cyclones, now let’s turn to another type of natural disasters Floods. Although it is a totally different type of natural disasters compared with tropical cyclones, it sometimes has close relationships with storms. So, I choose to explore secrets about Floods as the following part. 

But I should make it clear here that it does not mean all floods caused by tropical cyclones. Tropical cyclones is one of the reasons, sometimes, but not the only or necessary reason. Floods also come along with continuous heavy rains, large sea tidal surges, incompletely freeze/ thaw during winter/ spring or sudden destruction of some infrastructures such as dikes and dams. Furthermore, floods often lead to huge losses both in human life and economy. Let’s watch the general introduction video below to feel the tremendous power of floods.
