Tropical air masses form in low-latitude areas and are moderately warm. Polar air masses take shape in high-latitude regions and are cold. Equatorial air masses develop near the Equator, and are warm. Air masses are also identified based on whether they form over land or over water.

Jets streams play a key role in determining the weather because they usually separate colder air and warmer air. Jet streams generally push air masses around, moving weather systems to new areas and even causing them to stall if they have moved too far away.

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air.

Answer Expert Verified The answer is B (different temperatures meeting near the north and south poles. A jet stream can be defined as air current in fast motion at around 7-12km (4.3-7.4miles) above sea level.

A jet stream forms high in the upper troposphere between two air masses of very different temperature. The greater the temperature difference between the air masses, the faster the wind blows in the jet stream. Since it is horizontal air pressure differences that cause wind, this leads to very strong winds.

How Do Jet Streams Affect Air Travel? Jet streams are located about five to nine miles above Earth’s surface in the mid to upper troposphere — the layer of Earth’s atmosphere where we live and breathe. Airplanes also fly in the mid to upper troposphere.

Weather refers to the state of the atmosphere over an area at any point of time. The elements of weather and climate are the same, i.e. temperature, atmospheric pressure, wind, humidity and precipitation. On the basis of the monthly atmospheric conditions, the year is divided into seasons such as: Winter.

1 : the state of the atmosphere with respect to heat or cold, wetness or dryness, calm or storm, clearness or cloudiness. 2 : state or vicissitude of life or fortune. 3 : disagreeable atmospheric conditions: such as. a : rain, storm.

There are six main components, or parts, of weather. They are temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness. Together, these components describe the weather at any given time. Temperature is measured with a thermometer and refers to how hot or cold the atmosphere is.
