typhoon

• The government agency that is responsible for monitoring typhoons and weather disturbances, assessing and forecasting weather, flood, astronomy research and other conditions essential to the safety and welfare of the people.

  Philippine Atmospheric, Geophysical and Astronomical Services Administration
• The __ ___ generates the greatest number of tropical storms and cyclones.

  Pacific Ocean
• is a rapid rotating storm originating over tropical oceans from where it draws the energy to develop. It is referred to by different names depending on where they originate in the world.

  tropical cyclone
• The ______ is an imaginary line drawn around the Philippines. It was a zone given by the World Meteorological Organization to monitor for any weather disturbances in the area.

  The Philippine Area of Responsibility
• ____ occur in the Atlantic Ocean and the eastern north Pacific Ocean.

  hurricanes
• • ___ occur in the south Pacific Ocean and Indian Ocean.


  cyclones
• • ___ occur in the western Pacific Ocean.

  typhoons
• Tropical cyclones that enters the Philippine Area of Responsibility(PAR) are called ___ because they always form in western Pacific Ocean.

  typhoons
• __ is the day-to-day condition of the atmosphereat a particular time and place. It changes from day to day because air in the atmosphere is continuously in motion.

  Weather
• Weather Instruments:


  Anemometer, barometer, wind vane, rain gauge, thermometer
• measures the speed of wind.

  anemometer
• shows the direction of the wind.

  wind vane
• measures air temperature.


  thermometer
• measures the amount or level of rain collected over a period of time.

  rain gauge
• measure air pressure.


  barometer
• ____ are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator.

  Tropical cyclones
• Eventually, water vapor will undergo a process called ____, wherein it cools off and will become liquid again or water droplets, which forms into cloud.

  condensation
• Spinning of typhoon is because of the phenomenon which we call ____ which causes water and air to curve or change direction as they travel across the Earth's surface.

  Coriolis effect,
• The air in the Northern Hemisphere is deflected to ___

  right
• while air in the Southern Hemisphere is deflected to ___.

  left
• Because of the Coriolis force, the air of the typhoonthat came from the Northern Hemisphere curves going to the right and spins ___, meanwhile, the air of the typhoon that came from the Southern Hemisphere also curves, going to the left and spins ___


  counter-clockwise, clockwise
• parts of a typhoon

  eye, eye wall, rain bands
• - the center and most calm part of a typhoon.

  eye
• - the most violent part of a typhoon where winds and rains are at their strongest.

  Eye Wall
• - swirling clouds carrying rain and lightning that makes the typhoon bigger.

  Rainbands
• is also responsible for monitoring tropical cyclone occurrences within the Philippine Area of Responsibility or PAR which is bounded by an imaginary line drawn around the Philippines

  PAGASA
• PAGASA uses a system called _____ (PSWS) with four warning levels to describe the intensity of a storm.

  Public Storm Warning Signal
• - the increase in wind speed may occur abruptly or slowly. These changes in near landfall can lead to loss of lives and large damage to properties.


  strong winds
• - these are produced by tropical cyclone characterized by a violent and destructive whirling wind accompanied by a funnel-shaped cloud

  tornadoes
• - Rainfall associated with tropical cyclone is both beneficial and harmful. Rains contribute to the water needs of the areas traversed by the tropical cyclone. The rains are harmful when the amount is way too large as to cause flooding.


  rainfall and flooding
• - This is an abnormal rise of water due to tropical cyclone and it is an oceanic event. These devastating surges occur along coasts with low-lying terrain.

  storm surge
• The study of the formation and topography of mountains and hills is called

  orography
• Orographic lifting occurs when air flows over mountains and is forces to rise, causing rain or snow over the mountains, which is called

  orographic precipitation.
• is a dry area in the leeward side, which can be at risk for droughts.
