What kind of weather will a typhoon bring? What kind of damage will a typhoon cause?

When a typhoon moves towards land, due to the strong winds and low pressure of the typhoon, the seawater accumulates strongly towards the coast, the tide rises sharply, and the waves press towards the coast like a tidal wave. In addition, the secondary disasters of the typhoon include landslides and mud-rock flows caused by heavy rain. Let's learn about the destructive power of typhoons today.

What kind of weather does a typhoon bring?

The first is strong winds. Typhoon wind speeds are usually above 17 meters per second, and even above 60 meters per second. According to measurements, when the wind force reaches level 12, the wind pressure per square meter on the plane perpendicular to the wind direction can reach 230 kilograms. Therefore, typhoon winds and the waves they cause can throw a 10,000-ton ship into the air and break it in the middle, or push the ship inland; hurricane-level winds are enough to damage or even destroy buildings, bridges, vehicles, etc. on land.

The second is rainstorm. When a typhoon makes landfall, the rainfall center can drop 100 mm to 300 mm, or even 500 mm to 800 mm of heavy rain in a day. The flood disaster caused by typhoons and rainstorms is fierce and extremely destructive, and is the most dangerous disaster.

The third is the storm surge. When a typhoon moves toward land, the strong wind and low pressure of the typhoon cause the seawater to accumulate strongly toward the coast, the tide rises sharply, and the waves press toward the coast like a tidal wave. The storm surge of a strong typhoon can raise the coastal water level by 5 to 6 meters. If the storm surge meets the astronomical high tide level, it can produce high-frequency tides, causing the tide to overflow, the seawall to collapse, and houses and various construction facilities to be destroyed, towns and farmland to be submerged, causing a large number of casualties and property losses.

What damage does a typhoon cause?

Typhoon wind speeds are usually above 17 meters per second, or even above 60 meters per second. Therefore, typhoon winds and the waves they cause can throw a 10,000-ton ship into the air and break it in half, or push it inland. Especially in areas where buildings are not reinforced, the damage is even greater. Strong winds can also blow debris into the air, making the outdoor environment very dangerous. Once a typhoon lands, the center of the rainfall can drop 100 mm to 300 mm, or even 500 mm to 800 mm of heavy rain in a day. When the typhoon moves toward land, due to the strong winds and low pressure of the typhoon, the seawater accumulates strongly toward the coast, the tide rises sharply, and the waves press toward the coast like a tidal wave. Secondary disasters of typhoons include landslides and mud-rock flows caused by heavy rain.

How destructive is a typhoon?

A strong typhoon (maximum winds near the center are above level 14) is strong enough to damage or even destroy buildings, bridges and vehicles on land. The damage is particularly severe in areas where buildings are not reinforced. Strong winds can also blow debris into the air, making the outdoor environment very dangerous. Foen winds or tornadoes may also occur in the surrounding area.

Typhoons can cause persistent heavy rains. They interact with the southwest monsoon to produce a southwesterly flow, or with the northeast monsoon to produce a concomitant effect that doubles the rainfall. Heavier rainfall in mountainous areas may cause river flooding, mudslides, and landslides.
