Heavy flooding leaves 900 dead in Pakistan
Pakistan is accustomed to summer flooding, but this year’s monsoon season has been unlike any in recent memory.
The term “monsoon” doesn’t necessarily mean a downpour — instead it just describes a seasonal wind shift. During the summer months, air over the higher terrain of Tibet and, to a lesser extent, Afghanistan and Tajikistan heats up and rises. That “thermal low,” or resultant low pressure system, inhales moist flow off the Arabian Sea and Bay of Bengal.
