Excessive Monsoon Floods in Asia

According to NASA Observatory, the amount of rainfall accumulation across South and East Asia from June to July 20 this year breaks records. From the remotely-sensed estimate data that came from Integrated Multi-Satellite Retrievals for GPM, NASA noted high rainfalls across India. For example, in the northeastern state of Assam, it recorded a total of 89 centimeters of rain from June 1 to July 22. The figure this year, according to NASA, is 20 percent more than the normal. The rainfall caused massive flooding displacing thousands of people and killing dozens of people and animals in the Assam Kaziranga National Park.

In China, rivers and lakes overflowed to record high levels. Poyang Lake reached 22.6 meters on July 13, way above the 19.2 meters annual average maximum. All over China, flooding and landslides damaged structures and affected millions of people.

Monsoon rains also flooded Japan. Last June, western Japan got three times the average amount of rainfall. The torrential rains caused floods and landslides. The recent flooding brought the highest rain-related death toll in the country in more than three decades.

This year, according to NASA, "the low-pressure systems of Asia's summer monsoon have been strong and stationary, allowing to pick up even more moisture from the Indian and Pacifica oceans and deliver it to land."
