FRONTS: MEANING, TYPES AND CLASSIFICATION
Front is that sloping boundary which separates two opposing air masses having
contrasting characteristics in terms of air, temperature, humidity, density,
pressure and wind directions.
An extensive transitional zone between two converging air masses is called
“frontal zone or frontal surface”. The frontal zone is inclined at a low angle to
the earth’s surface.
TYPES OF FRONTS
There are four types of fronts on the basis of their features e.g.
1. Warm front
2. Cold front
3. Occluded front
4. Stationary front
a. WARM FRONT: Warm front is that gently sloping frontal surface along
which warm and light air becomes active and aggressive and rises slowly
over cold and dense air. The middle latitudes range in warm front is
between 1:100 to 1:400.
b. COLD FRONT: A cold front occurs when a cold air mass advances and
replaces a warm air mass. The cold air is denser and forces the warm air
to rise rapidly creating a steep boundary.
