Weader

• Weather


  Condition of the atmosphere at a particular location at any given time
• Climate


  Refers to the average weather of a certain location over a long period of time
• Tropical climate


  • High temperature
  • High humidity
  • Abundant rainfall
  • Wind speed
  • Wind direction
  • Atmospheric (air) pressure
• Temperature, humidity, and rainfall are the most important elements in determining weather and climate
• PAGASA - Philippine Atmospheric, Geophysical and Astronomical Services Administration
• Weather forecast


  Scientific prediction of the weather conditions in the future
• Tropical cyclone (typhoon)


  Categorized according to strength and max sustained winds at the center (also known as eye of the storm) and not by the amount of rainfall
• TCWS (Tropical Cyclone Warning Signs)


  Used to alert people about strength, impact, and possible damages by the incoming typhoon
• Tropical cyclone categories


  • Tropical Depression
  • Tropical Storm
  • Severe Tropical Storm
  • Typhoon
  • Super Typhoon
• Tropical Depression: 61 km/h or less
• Troposphere


  Lowest ozone layer nearest to the surface where weather exists
• Temperature


  Refers to a substance's hotness or coldness, or the amount of heat stored in an object
• Thermometer


  Used to measure temperature in degrees Fahrenheit or Celsius
• Stevenson screen


  • Louvers edges
• Humidity


  Moisture content in the air, influences comfort and likelihood of precipitation, measured by absolute (vapor present) and relative humidity (comparison to saturation), relative humidity increases as air cools, leading to saturation and dew point, dew point: temperature at which air becomes saturated and condensation occurs
• Wind

  Movement of air caused by pressure/temperature differences, direction and speed measured, blows from high to low-pressure areas, anemometer measures wind speed, influenced by pressure gradients, Earth's rotation (Coriolis effect), and friction
• Clouds


  Composed of water droplets/ice crystals
• Air pressure and wind


  Air flows from high to low pressure, influencing wind direction and weather patterns, pressure systems like highs and lows drive wind circulation
• Temperature, humidity, and clouds


  Cooling air leads to increased humidity, saturation, and cloud formation, affecting weather phenomena like rain, snow, fog, and dew, warm air holds more moisture, leading to more intense weather events when cooled
• Tropical Storm

  62 - 88 km/h
• Severe Tropical Storm

  89 - 117 km/h
• Typhoon


  118 - 184 km/h
• Super Typhoon

  185 km/h
• Other term for Intertropical Convergence Zone

  ITCH or Doldrums
