What are the final stages of a mid-latitude cyclone?
The final stage of the cyclone occurs when the loop formed by the cold front boundary surrounding the low-pressure pocket of warm air closes. This cuts off the supply of warm moist air and the lifting force caused by the interaction between the cold and warm fronts.
What are the 6 stages of a mid-latitude cyclone?
Stages of Cyclogenesis
- Stationary Stage. The first stage of cyclogenesis, the stationary stage, is named so due to the presence of a stationary front. …
- Wave Stage. …
- Open Stage. …
- Occluded Stage. …
- Dissipation Stage.
At which stage in the life cycle of a mid-latitude cyclone are we most likely to observe an occluded front?
As the mid-latitude cyclone reaches maturity, the central pressure will be at its lowest and the occluded front will begin to form (as the cold front catches up to the warm front).
What are the 3 stages of a cyclone?
The development of cycle of tropical cyclones may be divided into three stages. a) Formation and initial development (b) Full maturity (c) Modification or decay!
How many stages make up the life cycle of a mid-latitude cyclone?
9.2 Midlatitude Cyclones. The polar front theory, also known as the Norwegian model, states that cyclones have a reasonably predictable, six-stage life cycle.
What happens in a mid-latitude cyclone?
The swirling air rises and cools, creating clouds and precipitation. Mid-latitude cyclones form at the polar front when the temperature difference between two air masses is large. These air masses blow past each other in opposite directions.
What are mid-latitude cyclones quizlet?
A CYCLONIC STORM (A LOW) THAT MOST OFTEN FORMS ALONG A FRONT IN MIDDLE AND HIGH LATITUDES, OUTSIDE OF THE TROPICS.
What is a mid-latitude climate?
Moist continental mid-latitude climates have warm to cool summers and cold winters. The location of these climates is poleward of the “C” climates. The average temperature of the warmest month is greater than 50° F (10° C ), while the coldest month is less than -22°F (-30°C).
How is a mid-latitude cyclone formed?
Mid-latitude cyclones are the result of the dynamic interaction of warm tropical and cold polar air masses at the polar front. This interaction causes the warm air to be cyclonically lifted vertically into the atmosphere where it combines with colder upper atmosphere air.
How does a mid-latitude cyclone begin develop and disperse?
A mid-latitude cyclone begins when a relatively cold air mass and a warmer one meet along a frontal boundary. Here, cold and warmer air masses meet along a stationary front labeled “Cyclone A.”
How do mid-latitude cyclones affect South Africa?
South Africa is among a handful of countries that experience winter rainfall in some areas and summer rainfall in others. … This is because mid-latitude cyclones migrate further north during winter, allowing the edge of the cold front arm to sweep across the southern most part of the country.
What are the 4 stages of a cyclone?
An average life cycle of a cyclone is nine days and includes four stages: formative, immature, mature and decay. The formative stage is the first and develops from an area of strong convective cloud. Stage two (the immature stage) sees the beginning of gale force winds and the official naming of the cyclone.
What are the 5 stages of a cyclone?
This is the tropical cyclone category system as used by the Bureau of Meteorology:
- Category one (tropical cyclone) Negligible house damage. …
- Category two (tropical cyclone) Minor house damage. …
- Category three (severe tropical cyclone) …
- Category four (severe tropical cyclone) …
- Category five (severe tropical cyclone)
