In the Philippines, tropical cyclones (typhoons) are called bagyo. The term bagyo, a Filipino word meaning typhoon arose after a 1911 storm in the city of Baguio had a record rainfall of 46 inches within a 24-hour period..  Are the term Hurricanes, Typhoons, and Cyclones are the same?  The only difference between a hurricane, a cyclone, and a typhoon is the location where the storm occurs. Hurricanes, cyclones, and typhoons are all the same weather phenomenon; we just use different names for these storms in different places. When they form in the Atlantic or Eastern Pacific, the storms are called hurricanes. In the western North Pacific, they are called typhoons and in the South Pacific and Indian Ocean, they are called cyclones.  Northern Hemisphere tropical cyclones rotate in counter clockwise. Southern Hemisphere tropical cyclones rotate clockwise. What have you notice in the physical appearance of a typhoon?  ANATOMY OF A TYPHOON The EYE of a typhoon is an area with the lowest air pressure. Importance: While many The eye or the center is helpful for people think the weather forecasters and meteorologists eye is the because it serves as the reference point deadliest part of a in plotting the typhoon’s location. typhoon, it is the  ANATOMY OF A TYPHOON Surrounding the eye is the Eye wall, where the severe weather occurs. It is the innermost ring of convection near the center of the This is the zone where surface winds typhoon, packing reach their highest speed, bringing the the fiercest rains strongest thunderstorm activity. and most intense winds.  ANATOMY OF A TYPHOON Inner rainbands – these are the main spiral bands of a typhoon. These bands now appear organized and move inward (toward the center). In this part, there is moderate intermittent rains and winds of 63- 117kph.  ANATOMY OF A TYPHOON Outer rainbands – these outer spiral bands of a typhoon. These bands scattered and move inward. In this part, rainfall may be light to moderate, and wind speeds are up to 62kph. HOW DO TYPHOONS DEVELOP? Elements in forming a typhoon Sufficiently warm sea surface temperature Atmosphere instability High humidity in the lower to middle levels of the troposphere. Enough Coriolis effect to develop a rotating low pressure center A pre-existing low-level focus or disturbance Low vertical Wind shear  FORMATIVE STAGE IMMATURE STAGE MATURE STAGE DECAYING STAGE Where typhoons develop? Trade winds converge in a low pressure belt known as the Intertropical Convergence Zone or ITCZ ( Doldrums) How do we know that there is a typhoon? Typhoons are accompanied with a very strong winds of more than 118kph, heavy rains, and large tsunami-like ocean waves called storm surges. Why the Philippines is prone to typhoons? Philippines with the total area about 300,000 km/km. It is located along major typhoon belts. Of all three possible paths in the region, two of these always involve the Philippines. Why the Philippines is prone to typhoons? The Philippines is the largest country in the northern hemisphere closest to where the sources of typhoons are. Typhoons may develop in the West Philippine Sea. These typhoons move generally northward or toward the northeast, affecting the Philippines. Tropical Cyclone Classification The five categories are as follows: 1. Tropical depression: 61 kph 2. Tropical storm: 62 kph-88 kph 3. Severe tropical storm: 89-117 kph 4. Typhoon: 118-220 kph 5. Super typhoon: exceeding 220 kph  PHILIPPINE ATMOSPHERIC GEOPHYSICAL AND ASTRONOMICAL SERVICES ADMINISTRATION -It is an agency providing flood and typhoon warnings, public weather forecasts and advisories, meteorological, astronomical, climatological, and other specialized information. Here are some tropical cyclones that entered the Philippines.
