Typhoon is another name of the same weather phenomena called tropical cyclone in the Indian Ocean or Hurricane in the Atlantic or Typhoon in the North Pacific Ocean. Typhoon occurs in the Northwest Pacific Ocean between 180°E to 100°E. Typhoon or cyclonic storms are most active in this region. The Typhoon occurs throughout the year, as a result there is no specific Typhoon season in the northwest Pacific Ocean.
what causes typhoons
Typhoons are formed due to the presence of higher surface water temperature, Coriolis forces, high difference of temperature between the sea surface and the above atmosphere, atmospheric instability, and high humidity. Philippines, Japan, and China are the three countries, which mostly get affected by Typhoons throughout the year.
Recent Typhoons

Preventive Measures for Typhoons
Most of the Typhoons occurring in the northwest Pacific Ocean are intense, thus advance warning about the possible intensity of storm should be provided to the locals and if required timely evacuation should be done. Locals should stock themselves with enough food and potable water to survive the after effects of the heavy storm and flood.
