English: Several weeks of heavy monsoon rains in August 2019 swamped Burma (Myanmar) and southern and western India, unleashing destructive floods and landslides. Above-average monsoon rainfall caused rivers and streams to overflow their banks, while destabilizing hillsides in several regions.
The annual monsoon in south Asia typically has its greatest impact between July and September. India, for instance, receives roughly 70 percent of its annual rainfall from the monsoon. The rain is critical for replenishing freshwater supplies and for watering crops. But with at least 15 percent of the country prone to floods, the monsoon also leads to several thousand deaths each year. The image above depicts satellite-based measurements of rainfall from August 1–12, 2019. The darkest reds reflect the highest rainfall amounts, with many places receiving 60 centimeters (24 inches) or more during this period. The image below shows the totals after twelve days. The measurements are a product of Global Precipitation Measurement (GPM) mission, a partnership between NASA, the Japan Aerospace Exploration Agency, and five other national and international partners. The rainfall totals are regional, remotely-sensed estimates. Each pixel shows 0.1 degrees of the globe (about 7 miles at the equator), and the data are averaged across each pixel. Individual ground-based measurements within a pixel can be significantly higher or lower than the average. The data come from Integrated Multi-Satellite Retrievals for GPM (IMERG), a product of the GPM science team. IMERG compiles precipitation estimates from several satellites, as well as surface precipitation gauge data, to provide precipitation estimates between 60 degrees North and South latitude.Deutsch: Mehrere Wochen schwerer Monsunregenfälle uberschwemmten im August 2019 Myanmar sowie den Süden und Westen Indiens; sie setzten zerstörerische Überflutungen und Erdrutsche in Gang. Überdurchschnittliche Monsunegenmengen führten dazu, dass Flüsse und Ströme ihre Ufer überstiegen und in verschiedenen Regionen Bergflanken destabilisiert wurden.
Die jährliche Monsunsaison in Südasien hat üblicherweise ihre stärksten Auswirkungen zwischen Juli und September. India beispielsweise erhält ungefähr 70 Prozent des jährlichen Regens aus dem Mnsun. Der Monsunregen ist wichtig zum Wiederauffüllen der Süßwasservorräte und zur Bewässerung der Feldfrüchte. Weil allerdings mindestens 15 Prozent des Landes überschwemmungsgefährdet sind, verursacht der Monsun jedes Jahr bis zu mehreren Tausend Toten. Das obige Bild zeigt satellitenbasierende Messungen der Regenmengen zwischen dem 1. und 12. August 2019. Die am dunkelsten rot gefärbten Pixel stellen die höchsten Regenmengen dar, mit 600 mm oder mehr innerhalb dieses Zeitraums. Diese Messungen sind Ergebnis der Mission Global Precipitation Measurement (GPM), einer partnerschaftlichen Mission der NASA, der Japan Aerospace Exploration Agency und fünf weiteren nationalen und internationalen Partnern. Die Regenmengen sind regional, aber aus der Entfernung eingeschätzt. Jedes Pixel entspricht dabei 0,1 Längen- und Breitengrade des Globus, also etwa eine Fläche von 127 Quadratkilometern (ein Quadrat von 11,2 Kilometern Kantenlänge) am Äquator, und die Daten sind proPixel gemittelt. Die einzelnen tatsächlichen Messungen innerhalb dieser Fläche am Boden können deutlich höher oder geringer ausfallen als dieses Mittel. Die Daten kommen aus den Integrated Multi-Satellite Retrievals for GPM (IMERG) und sind ein Produkt des GPM-Wissenschaftlerteams. IMERG sammelt die Niederschlagsdaten von mehreren Satelliten, aber auch von Niederschlagsmessgeräten am Boden und erstellt daraus Niederschlagsmengenschätzungen für das Gebiet zwischen den 60. Breitengraden nördlich und südlich des Äquators. |
