Regional Gliding School Turbulence is an irregular motion of air resulting from “eddies” and vertical currents. Can cause light bumps or loss of control.

Air Masses and Fronts – II. Brief review An air mass is a large body of air whose properties of temperature and humidity are fairly similar in any horizontal.

4 3 . 8 Fronts

Transition zone between different air masses. COLD AIR mixing zone WARM AIR

The leading edge of an advancing cold air mass. Cold Front The leading edge of an advancing cold air mass. COLD AIR

SLOPE OF A COLD FRONT 1 MILE 50 MILES The slope of the front is very steep (1 in 50) Narrow weather band Can be very severe 1 MILE 50 MILES

Cold Front Clouds and weather clouds of vertical development showers winds veer temperature decreases behind front Fast moving cold fronts may produce severe thunderstorms and/or squall lines

NOTE: You must use the buttons in the Confirmation Stage

Meteorology Fronts Let's try a few review questions on Meteorology: Question #1 - The slope of a cold front is . A Shallow B Steep C Gradual Vertical D

The trailing edge of a retreating cold air mass Warm air is forced aloft by “overrunning”

SLOPE OF WARM FRONT FRONTAL SURFACE 1 MILE 150 - 200 MILES Shallow slope (1 in 200) Wide weather band that may extend up to 500 miles Extensive stratiform cloud FRONTAL SURFACE 150 - 200 MILES 1 MILE

Warm Front Clouds and weather stratus clouds steady precipitation winds veer temperature rises behind front thunderstorms may be embedded in the stratus clouds in winter, ice pellets and freezing rain may develop

Sequence of clouds indicating the approach of warm front are: C cirrus C cirrostratus A altostratus N nimbostratus S stratus

Meteorology Air Masses Congratulations!! You have now completed the Front lesson of the Meteorology Module. Of course, this lesson is always available to you for future reference if required. You are now ready to move along to the next Meteorology lesson you have not completed or to any other module you wish. You can advance to the Self Test Module if you feel ready to challenge the final exam. Good Luck!
