Cold and Warm fronts Often times when we experience a drastic change in weather, these changes occur from fronts. Both warm and cold fronts create sudden changes. These fronts are different air masses that separate at different densities. Zones are what separate the difference between warm and cold fronts. Often times between warm and cold front there are narrow lines and they`re typically shown by lines on a weather map. Usually, an air mass advance into the region occupied by another air mass. When two fronts collide this creates a midlatitude cyclone. Also, bringing much precipitation and severe weather to the area. There are five basic types of fronts- warm fronts, cold fronts, stationary fronts, occluded fronts, and drylines. Although, these are all important and have a big impact on our weather systems the most common are warm and cold fronts. Warm fronts are noted on a weather map often by a red line with semicircles indication the direction in which the front is heading. They often invade an area of cooler air, and bring warmer air to the area. “Warm fonts usually move from southwest to northeast and the air behind a warm front is usually warmer and moister than the air behind it (Climate&Weather. Web). They often come into play in the United States by (mT) or maritime tropical. This is where the warm air enters the borders from the Gulf of Mexico pushing over the land where cooler air exist. Generally when these fonts combine this produces all kinds of
2- Air pressure is not usually a constant that’s why usually impacts therefore it usually weather not climate. Some several key areas of the globe have consistent highs and lows that affect the weather and wind patterns having a huge impact on the climate.
There are three different weather bands in each hemisphere, they are trade winds, polar easterlies, and prevailing westerlies.
The red lines along the edge represent the warm air rising, and the blue lines along the edge represent the cold air falling.
The Pacific became cooler than normal as the Atlantic became much warmer. The two things did not combine good and reacted in the jet streams changing directions. The air current normally carries moisture from the Gulf of Mexico up toward the Great Plains. It then dumps rain when it reaches the Rockies. In return, when the jet streams moved south, rain never reached the Great Plains.
Although the weather is constantly changing, the climate for a general area can sometimes surprise you and change as well, especially in areas where the weather is considered “bipolar” since it changes so much.
According to this Chapter, the cause of these climate changes came from forcing. Forcing is any ongoing process or discrete event that alters the energy of the system. Examples of natural forcings include volcanic eruptions, periodic shifts in the Earths’s orbit and changes in the sun’s
Weather and climate are separate but related terms. The term weather refers to short-run atmospheric conditions that exist for a
It is not only the weather that the air masses bring that affects the climate of the UK, but also, the complex interactions between the air masses. Most importantly, the interactions between the Polar Maritime and Tropical maritime air masses can lead to the formation of areas of significantly low pressure called depressions. These depressions usually form in the Atlantic Ocean at the boundary between PM and TM air, and bring characteristic cloudy, wet and windy conditions. These depressions are what are responsible for many of the winter storms. They are regular occurrences and so contribute to the overall pattern of weather over a long period i.e. the climate of the British Isles. The interaction between continental air masses often leads to anticyclones which are the opposite of depressions – areas of significantly high pressure. They bring settled weather, with clear skies and light winds. In the summer they can be responsible for temperatures of over 30⁰C. Many say it is the pattern of depressions and anticyclones passing over Britain that is responsible for its
The term Climate Change refers to the changes in typical weather patterns for given regions- this
Climate change is a change in the average global or regional weather patterns. Climate changes includes factors such as; temperature, precipitation, humidity, wind and seasons, influenced by oceans, land surfaces and ice sheets. This plays a
The weather often parallels
When climate change occurs; there is increase in temperature. When temperature rises, unusual changes occur on Earth. For example, it can result into more floods, droughts, or intense rain, as well as severe heat waves. Oceans and glaciers have also experienced some changes. According to NASA: Sea levels have risen 3 inches and extreme weather in the U.S. has increased by 30 percent. In Greenland and Antarctica, ice sheets have lost 4.9 trillion tons of ice.
So the warm moist air creates clouds of rain and thunderstorm. Adding to that winds with different speed going in different directions assisting in expanding these great clouds of rain and thunderstorm. With
Warm water is crucial thus why we only see hurricanes in tropical regions that are close to the Equator.
The process begins when the sun starts to heats up the surface which creates warm air. The warm, less heavy air rises and converges with the cold less heavy air above. This process is known as wind shears. Wind shears are when two
