What happens to wind during a cold front?

What happens to wind during a cold front?

As the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning. Atmospheric pressure changes from falling to rising at the front.

Do cold fronts bring high wind?

In the spring, these cold fronts can be very strong, and can bring strong winds when the pressure gradient is higher than normal. During the winter months, cold fronts sometimes come through an area with little or no precipitation.

What happens to air pressure when a cold front passes?

After the cold front passes a point, winds turn to the west, northwest, or north. Since the cold air is very dense it is very effective at displacing the warm air ahead of it. Air pressure usually falls as a cold front approaches, rising rapidly after passage as the dense cold air moves in.

How does a cold front occlusion develop?

A cold occlusion occurs when the air behind the occluded front is colder than the air ahead of it. The cold air behind the front is less dense than the even colder air ahead of it, and so it passes over the top of the colder air.

What happens in a low pressure area?

A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation. Winds blow away from high pressure.

What countries are on the 30th parallel?

The 30th parallel north is a circle of latitude that is 30 degrees north of the Earth’s equatorial plane….Around the world.
