199 1 On April 29th, the sky in the Bay of Bengal was different from before. Sunrise in the morning, sunset at night, the sky was covered with a bright orange, and then gradually turned bronze, and then a dark gray area appeared on the horizon.

On this day, countless seabirds flew screaming from the Bay of Bengal. This phenomenon is rare on weekdays.

At night, the sky suddenly turned sunny and cloudy, and the rolling clouds covered the sky. In an instant, the strong storm in the Bay of Bengal thundered and thundered, sweeping the coast of the Bay of Bengal and all its islands at a speed of 66.7 meters per second. Where the storm passed, old trees were knocked down, houses were destroyed, broken walls were swept into the sea, ships sailing at sea were sunk, ships moored in ports were thrown ashore, and people and animals were swept into the air and disappeared. ...

After the storm, there was a tsunami in the northern Bay of Bengal. Strong winds set off huge waves as high as 6-9 meters, sweeping the coast of the Bay of Bengal and its islands with thunderous force. Many ships were smashed and the solid breakwater was washed away by the driving waves. Residents of coastal islands and their shelters were washed away without a trace. When the waves receded, the beach was in tatters and chaos, and the bodies were lying there in a mess, which was very miserable.

◎ Bangladesh is located in the southeast of Ganges Delta, in the north of the Bay of Bengal, with the East Ghats in the west, the Arakan Mountains in the east and the Himalayas in the north. In addition, it is located in the monsoon region, and the southwest monsoon blowing from the Indian Ocean rushes to the low pressure region with warm and saturated water vapor. It is blocked by the mountain, and it will rain soon. And there are 230 rivers in Bangladesh, which will be flooded every rainy season. All these factors make Bangladesh, which is flat and low-lying, unable to escape the flood.

Due to its special geographical location, Bangladesh has always been a country with frequent floods:1970165438+10/2, a tropical storm "born" in the Indian Ocean killed 300,000 people and left 6,543,800+homeless. 1976 10, the tropical storm in the Bay of Bengal caused seawater to flow backwards, causing 654.38+10,000 people to die in this disaster; 1The catastrophic flood in July 1987 killed more than 2,000 people.
