What brings dry and clear weather?
Air Masses and Fronts
| A | B |
|---|---|
| stationary front | a cold air mass meets a warm air mass; they each stay still and cause many days of cloudy, wet weather |
| cyclone | low pressure in the middle;winds spiral inward; brings stormy weather |
| anticyclone | high pressure in the middle; winds spiral outward; brings dry, clear weather |
What pressure system brings dry clear skies?
Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day.
What front causes dry clear conditions?
Stationary Front In a front of this kind, neither the cold air mass nor the warm air mass is moving. Winds tend to blow along it in opposing directions on each side. Conditions along the front are clear and dry, however, if moisture is available near the front, clouds and light precipitation may develop.
What front brings clear skies?
Cold fronts usually bring cooler weather, clearing skies, and a sharp change in wind direction.
What front brings lots of rain?
Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth’s surface.
What are the symbols for a dry cold air mass?

| cP | the two-letter symbol used to indicate a cold air mass that formed over land |
| mT | the two-letter symbol used to indicate a warm air mass that formed over water |

Which cities are experiencing clear dry conditions?
Which cities are experiencing dry, clear conditions? Seattle, New York city, Washington D.C.
What causes areas of high and low pressure?
The Earth’s atmosphere exerts pressure on the surface. Areas of high and low pressure are caused by ascending and descending air. As air warms it ascends, leading to low pressure at the surface. As air cools it descends, leading to high pressure at the surface.
Which cities are experiencing dry clear conditions?
What weather do cold fronts bring?
A cold front forms when a cold air mass pushes into a warmer air mass. Cold fronts can produce dramatic changes in the weather. 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.
What type of front brings severe weather?
Cold fronts occur when warm air is pushed up into the atmosphere by colder air at the ground. These fronts tend to move faster than the other types of fronts and are associated with the most violent types of weather such as severe and super cell thunderstorms, although any type of front can produce these same storms.
What kind of weather does a warm front bring?
stormy weather
Warm Front Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth’s surface.
