    <p>air, planet, temperature, atmosphere</p> Signup and view all the answers

    Explain the entire process of Global Atmospheric Circulation in detail.

    <p>At the equator, the air is warm due to heating from the sun. This creates low pressure at the surface and produces powerful storm clouds with torrential rain. As the air rises, it cools and hits a 'lid' called the tropopause. The cooler air then moves towards the poles, sinking around 30 degrees north and south of the equator, which creates high pressure at the surface. The air diverges, with some returning to the equator and other air moving toward the poles. At about 50 degrees north and south, the air diverges with the travelling to the poles sinking and creating high pressure.</p> Signup and view all the answers

    Explain in detail the formation of a tropical revolving storm.

    <p>A tropical revolving storm forms over warm ocean waters, usually when sea surface temperatures are above 27 degrees Celsius. Moisture evaporates from the ocean surface, rising into the atmosphere and cooling to form clouds and thunderstorms. This process causes the air to warm and rise further, creating low pressure at the surface. The Earth's rotation causes the storm system to begin rotating, and as it organizes, it can intensify into a tropical cyclone.</p> Signup and view all the answers

    Study Notes

    Definition of a Tropical Cyclone

    • Movement of air around the planet, influencing atmospheric temperature, especially around the poles.

    Global Atmospheric Circulation

    • Describes and explains the process of global atmospheric circulation.
    • Includes polar, Ferrel, and Hadley cells.
    • Summer and autumn periods between the equator are notable for the Coriolis effect.

    Tropical Cyclone (TRS) Conditions

    • TRS (Tropical Storm) conditions are often characterized by unstable atmospheric conditions.
    • Unstoppable rising air and high water temperatures contribute to TRS formation.
    • TRS are very fussy and particular conditions.

    Tropical Cyclone Formation

    • The conditions for TRS formation are complex.
    • Typically develop between the tropic of cancer and the tropic of Capricorn.
    • For example, in the Indian and Pacific Ocean regions.
    • An anomaly exists where tropical storms form beyond the tropics, for instance, along the east coast of the USA/South West Australia. These are often referred to as "anomalous" tropical storms.

    TRS Structure

    • Warm, moist air rises creating towering cumulonimbus clouds.
    • Cold dry air sinks creating clear skies and high pressure.
    • The eye of the TRS is the calmest part, with high pressure, no wind and around 20-40 miles wide.
    • The wall is the most dangerous part of the TRS, with the most powerful winds.
    • There is a cirrus shield that is dome-like, and visible from space.
    • The eye is in the middle and can be seen from space.
    • Low pressure, high moisture containing air and old sinking air creates the eye.

    TRS Distribution

    • Describes the global distribution of tropical storm regions.
    • Some anomalies in the formation of tropical storms exist beyond the tropics, for instance, along the east coast of the USA/South West Australia. These are often referred to as "anomalous" tropical storms.

    TRS Strength and Characteristics

    • TRS peak temperatures around 27°C are typical.
    • TRS intensity can vary by location.
    • A storm surge can occur, displacing water around the TRS, caused by the "weight" of the TRS on the ocean surface.
    • TRS can have a peak intensity.
    • TRS are measured on a scale.
    • Frequency of TRS may fluctuate over time. For example, in 1935 the number of named storms was 10.5, and in 1955 the number was around 9.
    • However, from 1940 the number of named storms continuously increases by each year.
