Typhoon

What is the Typhoon?

A tropical depression(TD) is the term used for a tropical system that has wind speeds not exceeding 17m/s. A tropical storm(TS) should exceed its sustained wind speeds of 17 to 24m/s. Should the storm reach sustained wind speeds of 25 to 32m/s then it will be classified as a severe tropical storm(STS). Tropical cyclones that achieve peak winds in excess of 33m/s are popularly referred to as typhoons.

There are several atmospheric conditions could cause a typhoon to form. A pre-existing disturbance, warm ocean water, low atmospheric stability, sufficient Coriolis force, and upper atmosphere divergence are all important factors for typhoon formation.

Typhoon alert?

As a result of the typhoon, hurricane winds, storms , heavy rain, storm surge reach the standard for advisory. In that case, the typhoon advisory will be issued.

Details about Typhoon Causes

The first cause is warm water. When there is an abundance of warm water, there is a considerable amount of energy for the typhoon. Water at temperatures of 26.5°C is needed at a depth of 50 meters or more. If there is not this much available water at the right temperature, a typhoon won’t form. Warm water, when it mixes with cold air, creates a low pressure system. This is the start of that typhoon.

The next cause is the abundance of water. Once the typhoon has developed, it needs to be continuously fed. Therefore, high humidity is a must near the eye of the storm. As more heat meets with cold air, it results in more low pressure systems which gets the wind moving even more.

The big question, though, is where does the low pressure winds come from? When the northeast and southeast trade winds converge on each other, this results in a cooling of the air. This cooling is what meets up with the warm water and starts to cause the basis for a typhoon formation. If these winds never meet, there won’t be a typhoon because there won’t be a low pressure system.

One final necessity for a typhoon is location. For a typhoon to develop, it needs to be five degrees north of the Equator. That is the optimal location for typhoon development. Because of how precise it is, one would assume that typhoons are rare. However, some scientists suggest that the planet warming is a direct connection to the number of typhoons that a region has.
