Why does air pressure increase after a cold front passes?
If the air is moist and unstable enough, rain and thunderstorms can accompany the passage of the front. Air pressure usually falls as a cold front approaches, rising rapidly after passage as the dense cold air moves in. The dew point falls indicating the change to a dry air mass.
What happens at a cold front quizlet?
cold front is defined as the leading edge of a cooler and mass of air, replacing (at ground level) a warmer mass of air. A weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena.
How the weather are associated with anticyclones?
The eventually warmer and drier air suppresses cloud formation and thus anticyclones are usually associated with fine weather in the summer and dry, cold, and sometimes foggy weather in the winter. Calm settled weather is usually synonymous with anticyclones in temperate latitudes.
Why anticyclones bring clear skies and sunshine?
In summer, the clear settled conditions associated with anticyclones allow the Sun’s light to warm the ground. This can bring long sunny days and warm temperatures. The weather is normally dry, although occasionally, very hot temperatures can trigger localised thunderstorms.
Why are anticyclones not generally associated with clouds and rain?
Why are anticyclones not generally associated with clouds and rain? Air in anticyclones undergoes warming as the air descends. How would a moving object in Earth’s atmosphere be deflected as a result of Earth’s rotation?
How does the weather change as a depression passes over a location?
An area of low pressure is called a depression . Air rises in a depression so clouds and rainfall are formed. Depressions therefore bring unsettled weather and rain. Winds are normally stronger.
How would you identify a depression on a synoptic chart?
A depression, as its name implies, is a region of low barometric pressure and appears on the synoptic chart as a set of closed curved isobars with winds circulating anticlockwise in the northern hemisphere, clockwise in the southern hemisphere.

Is Bay of Bengal dangerous?
What makes the Bay of Bengal so deadly? The worst places for storm surges, say meteorologists, tend to be shallow, concave bays where water, pushed by the strong winds of a tropical cyclone, gets concentrated or funnelled as the storm moves up the bay.
