Weather Disturbances Typhoon/Hurricane Tropical Cyclones Tornado Tsunami

Typhoon/Hurricane Tropical Cyclones Tornado

- A large heat engine, where great amounts of heat are being produced from the process of latent heat of condensation.

- Both are names of tropical storms and most of their characteristics are the same. They have

- wind speeds that are more than 74 mph, and are accompanied by hail, strong winds, storm surges and rain. 

Hurricanes damage more land areas than Typhoons, which cause damage to countries’ coastlines.

Hurricanes move both clockwise and counter clockwise.

Typhoons are said to be stronger than Hurricanes because it develops where water is warm.

Typhoons move clockwise.

 

Pre-existing disturbance Warm ocean water Low atmospheric stability Sufficient Coriolis force Low vertical wind shear Upper atmosphere divergence

pre-existing system of disturbed weather

Around 19 tropical cyclones or storms The Philippine Atmospheric,

Geophysical and Astronomical Services Administration (PAGASA) releases tropical cyclone warnings in the form of Public Storm Warning Signals.

- Torrential rain that can cause flooding

- Extremely strong winds that carry debris that can be lethal

- Damage buildings and property- Destroy crops- Capsize boats at sea- Deaths due to drowning- Infrastructure destroyed

Land encourages the development of a tornado, while it destroys the cyclone’s formation.

The time frame from the birth of a tornado until it dies out, is generally measured in minutes.

Cyclones develop and faster over the oceans.

The cyclone has a longer life span. The time frame from the birth to the death of a cyclone, is measured in hours and days.

Effects on Nature

Tsunami are ocean waves, that can reach the height of 100 feet, and crash onto land.

Japanese word that means “harbor wave”.

80% of all tsunamis take place in the Ring of Fire in the Pacific Ocean.

Tsunamis are formed as a result of powerful under water earthquakes, volcanic eruption, or a landslide

Some parts of the Ocean experience frequent earthquakes because of the movement of the continental plates.

In deep open sea, tsunamis move at a speed of 600 mph or more.

When tsunami arrives at the shore, it usually decreases its speed to about 45 mph/hour.

Tsunami may affect people mentally, emotionally, and financially.

People are left homeless and careless due to the flooding and other destructions.

Lost of lives

Destroy the crops and flood the city. A tsunami can cause plenty of damage

by crushing buildings, sweeping people of their feet, and dirtying the pipes, consequently spreading disease.
