EARTH AND SPACEModule 2: UNDERSTANDING TYPHOONS

Why is Philippines prone to typhoons? because it lies astride the typhoon belt, in the active volcanic region known as the "Pacific Ring of Fire,"What conditions favor the formation of typhoons? atmospheric instability a pre-existing low level focus or disturbance high humidity in the lower to middle levels of the troposphereWhat have you experience during typhoon? Floods, Landslide, Excessive rain, Strong windsWhat is a typhoon? a type of large storm system having a circular or spiral system of violent winds "Typhoon" is the name of these storms that occur in the Northwestern Pacific.

Maglev(derived from magnetic levitation) In the northern hemisphere, the winds blow in a counter-clockwise direction. In the southern hemisphere, the winds spin around in the opposite direction, clockwise. PAR(Philippine Area of Responsibility) includes a big area east of the Philippines because this is where most tropical cyclones come from.

PAGASA (Philippine Atmospheric Geophysical and Astronomical Services Administration) a sector of the philippine government observes typhoons via radio satellite
