A wind system that circulates around a low pressure center
What a tropical cyclone is called depends on where it originates from
Tropical cyclone
Uses warm moist air as fuel
Usually form in warm oceans near the equator
Tropical cyclone formation
1. Warm air rises and leaves an area of low pressure near the surface
2. Surface wind converges as warm air rises which consequently creates a low pressure center
3. Air accumulates then condenses to form clouds
Pressure gradient
The pressure difference between two areas
Pressure gradient
Greater pressure gradient means greater wind speed
Factors affecting cyclone formation
Friction slows wind speed
Coriolis effect deflects wind as a consequence of the rotation of Earth
Thunderstorm is a localized weather disturbance characterized by rainfall with occurrence of thunder and lightning
Classification of tropical cyclones
Tropical depression: with speeds of up to 61 kilometers per hour (kph)
Tropical storm: with speeds ranging from 62 to 88 kph
Severe tropical storm: with speeds ranging from 89 to 117 kph
Typhoons: with speeds ranging from 118 to 220 kph
Super typhoon: with maximum speed exceeding 220 kph
PAGASA
Philippine Atmospheric Geophysical and Astronomical Services, the government agency responsible in monitoring typhoon and providing information on weather updates
Fujiwhara (or Fujiwara) effect
The interaction between two nearby tropical cyclones, also known as a binary interaction
