Factors that aggravate storm surge in Ganges estuary

The factors that aggravate the storm surge in Ganges estuary are as follows:

1, trumpet-shaped, with a large mouth and a small inside. When the offshore tide rushes to the estuary, the water level rises;

2. Due to the jacking effect of the river, the river flows in the opposite direction to the tide, and the tide level rises due to the jacking effect of the river;

3. Affected by the summer monsoon. The southwest monsoon prevails in summer, and the tides are strengthened by wind.

There are many hurricanes and storms in summer, which aggravate the tides.

Storm surge is a catastrophic natural phenomenon. Due to severe atmospheric disturbances, such as strong winds and sudden changes in air pressure (usually referring to disastrous weather systems such as typhoons and extratropical cyclones), when the sea water rises and falls abnormally and overlaps with astronomical tides (usually referring to tides), if this superposition happens to be the superposition of high surges formed by strong and low-pressure storm surges and astronomical climaxes, it will form stronger destructive power.
