Transcript of "19. forecasting the weather notes"

  1. 1. Shows a summary of current weather conditions at a particular weather station
  2. 2.  lines connected areas of the same temperature
  3. 3.  lines connecting areas of the same air pressure
  4. 4.  when isobars form circles they designate the center of high or low pressure, labeled with an H or L
  5. 5.  Thermometer – measures temperature  Barometers – measures air pressure  Anemometer – measures wind speed  Wind Vane – measures wind direction
  6. 6.  uses reflected radio waves to determine the velocity and location of objects, can detect the precise location, movement, intensity of precipitation, wind patterns, and severity of the storm
  7. 7.  Move from high pressure to low pressure a) High Pressure – sunny calm weather b) Low Pressure – can mean storminess, fronts extend from them
  8. 8.  move by global winds and the jet stream a) Arctic/Polar – typically move to the South and West b) Tropical – moves to the North and East c) Bring characteristics of where they formed, the longer they are stationary the more they exhibit the characteristics of that region, they change as they move
  9. 9.  Cold Front – preceded by strong thunder and snow storms, after it passes temperatures drop sharply and pressure rises rapidly  Warm Front – thick, low level clouds, wide spread precipitation  Stationary Front – similar results as a warm front, just over longer period of time  Occluded Front – large scale precipitation and widespread rain and thunderstorm
  10. 10.  The higher the dew point, the more water in the air, thus higher chance of precipitation
  11. 11.  If air pressure is dropping, a storm could be on the way
  12. 12.  Wind follows the isobars, the closer they are together, the stronger the winds due to the larger pressure gradient
  13. 13.  High altitude, narrow bands of wind that typically go west to east, dictate weather pattern and air mass movement, stronger during winter due to larger temperature differences between poles and equator
  14. 14.  Generally weather patterns move from west to east due to global winds (prevailing westerlies)
