Philippine Area of Responsibility *(PAR) “ 16  Tracking of a typhoon ▸Typhoon tracking and forecasting involve the prediction of the path of a typhoon every 6 to 12 hours over a period of at least five days. ▸With this, PAGASA uses a variety of meteorological tools and methods to deliver accurate forecasts. ▸The weather in a specific location will show signs of an approaching typhoon, like an increasing wave height and frequency, increasing cloudiness, falling air pressure, and heavy rainfall. 17  Tracking of a typhoon ▸Accurate track prediction depends in the position and strength of high- and low-pressure areas, and on how those areas will migrate during the lifetime of a tropical system. ▸Computer forecast models aid in determining this motion at least 5 to 7 days ahead. ▸An accurate track forecast is essential because if the track forecast goes wrong, the intensity, rainfall, storm surge, and tornado threat will also be incorrect. 18  Tracking of a typhoon ▸Accurate track prediction depends in the position and strength of high- and low-pressure areas, and on how those areas will migrate during the lifetime of a tropical system. ▸Computer forecast models aid in determining this motion at least 5 to 7 days ahead. ▸An accurate track forecast is essential because if the track forecast goes wrong, the intensity, rainfall, storm surge, and tornado threat will also be incorrect. Weather Surveillance Radar 19 Dissecting a Typhoon 20  Dissecting a Typhoon ▸Location A is the eyewall of the typhoon. B, C, and D are locations that are getting farther from the eye. The air pressures at the different locations are: 21  Dissecting a Typhoon ▸Location E is within the eye of the typhoon. Location F is within the clouds surrounding the eye. The clouds at F make up the eyewall. The wind speeds at the two locations are: 22  Tracking of a typhoon ▸Accurate track 23  Tracking of a typhoon ▸Accurate track 24  Tracking of a typhoon ▸Accurate track 25  Tracking of a typhoon ▸Accurate track 26  Tracking of a typhoon ▸Accurate track 27  Tracking of a typhoon ▸Accurate track 28  Tracking of a typhoon ▸Accurate track 29  Tracking of a typhoon Tropical Storm (TS) wind speed: 66 t0 88 kph 30 Answer me! ▸Where did tropical storm Sendong start to form?
