Triangle will show the direction the front is moving in. On a weather map, the cold front is represented by a blue line. The rain will stop and Cumulous Clouds are replaced by Stratus clouds or with clear skies. After the Cold front moves through the area, the temperatures become cooler. Atmospheric pressure changes fast from falling to rising. They can move twice as fast as a warm front. These dramatic changes in the weather are fast and violent. Thunderstorms and heavy rainfall with hail can develop.
When Cold fronts come through the weather becomes windy and gusty. The warm air masses rise and the two cold masses meet in the middle. Occluded Front-This front occurs when warm air mass gets caught between two cold air masses.Stationary Front– This front occurs when warm and cold air meet and neither air mass has the strength to push the other they remain standing still.Warm Front-This forms when warm moist air slides up and over a cold air mass.Cold Fronts-When a cold air mass pushes under a warm air mass forcing the warm air to rise.There are four types of Fronts and they are: Usually, hundreds of miles long, when a front passes through a region, it changes the weather. The boundary between the air masses is part of the front. When large masses of warm or cold air move throughout the atmosphere they carry their own differences and characteristics. The constant movement of these accumulations of air is called Fronts. Elsewhere cooler denser air sinks pushing air outward to flow along the surface and complete the cycle. When the air in one region is warmer than the surrounding air it becomes less dense and begins to rise drawing more air in from underneath it. The differences in these temperatures create a restless movement of air and water in great swirling currents that distribute heat energy across the planet. Although daily changes in weather are due to winds and storms, the seasonal changes we live with are due to the earth revolving around the sun.īecause the earth is round and not flat, the sun’s rays don’t fall evenly on the land and oceans. Weather is the state of the atmosphere at any given time including things like temperature, precipitation, air pressure, and cloud cover. There are other conditions and characteristics of the earth’s atmosphere that can affect Winds and Storms and how they develop and move in continuous motion keeping weather constantly changing. The simple answer is that Weather can constantly change so quickly and drastically because of Winds, Storms, and the constant movement of accumulations of air called Fronts. What causes The Constant Changes in Weather? Did you ever wonder how the weather can change as quickly as it does? By the time it takes to put a cover on a baseball field because of a rain delay, it’s time to take it off and play ball again.
