[I]n Bangladesh, record rainfall has pushed rivers to some of the highest levels ever recorded. The result has been the forced displacement of 368,000 people to 970 temporary shelters as 1.3 million are afflicted by flooding. Tragically, 27 Bangladeshis have also lost their lives due to the extreme flooding. Rainfall rates of up to ten inches per day are contributing to the severe flooding even as water from floods further upstream in India and Nepal are flowing into Bangladesh river systems.
Overall, these various events may appear to occur separately. However, they are all associated with a very severe Equatorial rain pattern developing from Africa through Southeast Asia and stretching into the Atlantic inter-tropical-convergence zone during 2017. The apparently increased thunderstorm activity is now impacting everything from the intensity of monsoonal rains over Southeast Asia, the severity of storms in the Sahel of Africa, and the early formation of tropical cyclones off Cape Verde during August.
These heavy rainfall features are arguably linked to the climate-change based intensification of the hydrological cycle and, particularly, to the increasing intensity of Equatorial thunderstorms. The overall climate and weather trend for the larger region should thus be noted and these various related events should not be viewed in isolation.
