Smyrna Middle School

Winter 2013

water in the air
Water in the Air
  • Evaporation is when water changes from a liquid to a gas.
  • When air reaches its dew point relative humidity is at 100%
clouds
Clouds
  • Nimbostratus clouds will bring light to heavy continuous rainy weather.
  • Cumulonimbus clouds are large thunderstorm clouds that produce precipitation.
  • Altocumulus clouds are puffy mid-level clouds.
  • Cirrus clouds are high clouds made of ice crystals.
precipitation
Precipitation

• Sleet-Starts as rain then freezes in the air.

  • Snow-Water vapor changes directly into a solid because of cold temperatures.
  • Hail-Forms when precipitation is sent back up into the clouds many times.
air masses
Air Masses
  • Continental polar (cP) dry and cold
  • Maritime polar (mP) wet and cold
  • Continental tropical (cT) dry and warm
  • Maritime tropical (mT) wet and warm
  • C=dry
  • P=cold
  • M=wet
  • t-=warm
fronts
Fronts
  • Warm front-warm air moves over cold air and replaces it.
  • Stationary front-Not moving. Brings many days of cloudy, wet weather.
  • Cold front-cold air mass displaces a warm air mass.
  • Occluded front-warm air mass is caught between two cold air masses and is forced to rise. Lots of precipitation.
meteorology
Meteorology
  • Images of weather systems on television come from weather satellites.
  • From a weather map you can tell the locations of cold and warm fronts.
  • The lines connecting points of equal pressure on weather maps are called isobars.
  • Isobars help meteorologists by showing areas of high and low pressure.
