Question

A meteorologist observes a decrease in barometric pressure and predicts a chance of light to moderate precipitation. Which frontal system
is most likely approaching?

Answer 1

Answer:

Warm front

Explanation:

A warm front is the transition zone of the replacement of a cold air mass by a warm air mass. The pressure centers of warm fronts are usually low and the pressure read by a barometer will decrease due to an incoming warm front

The general direction of motion of warm fronts is from southwest to northeast with warmer and moist air behind the warm front than air into which the front flows. Therefore, warm fronts normally results in moderate precipitation or rainfall or snow.

Answer 2

The frontal system that is most likely approaching is a WARM FRONT.

• A warm front occurs when a warm air mass moves over a cooler air mass.

• The cooler air mass is denser, thereby remaining close to the ground.

• A warm front is generally associated with low pressure centers.

• The low pressure centers show lower pressure at the center compared to the outside.

• As the air rises, water vapor within condenses into water droplets, thereby forming clouds and thus also precipitations.

In conclusion, the frontal system that is most likely approaching is a WARM FRONT.
