What is the importance of weather disturbances?
A weather disturbance is a general term that describes any pulse of energy moving through the atmosphere. They are important in that they can act as focusing mechanisms for storm formation, or even to intensify low pressure systems.
How do winds affect weather?
Wind carries moisture into an atmosphere, as well as hot or cold air into a climate which affects weather patterns. Therefore, a change in wind results in a change of weather. Wind travels from areas of high pressure to areas of low pressure. Additionally, heat and pressure cause the wind to shift direction.

What is the most common mechanism that causes Typhoon development?
Answer: The most common mechanism to cause a typhoon to develop is the monsoon trough. This is an extension of the Inter-Tropical Convergence Zone where cyclonic spin has developed. The ITCZ is a zone of wind convergence of the northeast and southeast trade winds.
Why is Philippines always hit by typhoon?
The Philippines is prone to tropical cyclones due to its geographical location which generally produce heavy rains and flooding of large areas and also strong winds which result in heavy casualties to human life and destructions to crops and properties.
Why is the Philippines prone to natural disasters?
