Title: Weather Systems


1
Weather Systems As Heat Engines
2
Weather Moisture from the Caribbean
Humid hot air streams from the Caribbean
northward across Florida and up through the
Carolinas. Satellites show the clouds and
Doppler radar clearly shows moisture
concentrations in these clouds.
3
HOT TROPICAL MOIST AIR
  • The first ingredient for a storm. This may have
    embedded thunder storms tornadoes hail rain . . .

4
Doppler Radar Detects Moisture
  • The heavy rain is likely thunderstorms and
    possibly tornadoes but certainly large amounts of
    energy are indicated as moisture condenses.
    (2026J/g).

5
Animations
  • Animations show a developing heat engine
    weather system on the move.

6
Temperature Difference
  • The other ingredient to an intensified weather
    system is a boost in efficiency. A cold blast of
    air from northern Quebec provides a heat sink and
    therefore a boost to the system.

7
Weather Advisory Outlook
  • Intensifying storm is predicted to approach
    Atlantic Canada.
  • The prediction of an intense winter storm is as
    you see it at the right. The date of this
    prediction is Saturday March 3rd.

8
Sunday, The storm develops. . .
  • The storm intensifies and moves to the northeast
    as predicted.
  • Where is the moisture?

9
Mondays Prediction
  • Where is the Jet stream? This will determine
    where this monster goes from here?

Analysis
If you look at the AccuWeather Color Water Vapor
Satellite Loop you can see the ingredients for
this March blizzard. Number one, a ribbon of
moisture (shown in green) extending from the
Yucatan across Florida to the Northeast. Next, an
upper-level system, which is weakening, rotating
over western Tennessee. Finally, a vortex south
of Hudson Bay which will rotate southwestward
then southeastward, bringing cold air and extra
energy into the storm system in the Northeast.

  • Six hour cloud animation shows the moisture train
    still streaming from the Caribbean Northward.
  • Forecast now shows moisture animation to the NE
    seaboard.
