Understanding Wind and Atmospheric Pressure

The movement of air molecules in the atmosphere, usually from a high-pressure area to a low-pressure area.

Areas with higher temperatures have rising air, creating low atmospheric pressure. Areas with cooler temperatures have sinking air, creating higher atmospheric pressure.

A theoretical model explaining the movement of air between 35° and 60° North/South latitude, characterized by poleward and eastward surface air movement.

Air rises near the poles, travels towards the poles, then sinks creating areas of high pressure, generating eastward surface winds called 'polar easterlies'.

Locations where air descends, creating high atmospheric pressure.

Locations where air ascends, creating low atmospheric pressure.

A pattern of winds created by temperature differences between land and ocean surfaces.

Land warms more quickly than the sea during the summer, drawing moist air from the ocean, causing rain.

Land cools faster than the sea during the winter, causing dry winds to blow from land to the ocean.

Caused by air rising and sinking due to temperature differences within the troposphere, with three main cells: Hadley, Ferrel, and Polar.

The dominant wind pattern in the tropics, characterized by air rising at the equator, moving poleward, and descending at 30° North/South.

The Coriolis effect causes the Hadley Cell's winds to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

The winds in the Hadley Cell that blow towards the equator, divided into northeast trade winds in the Northern Hemisphere and southeast trade winds in the Southern Hemisphere.

The tendency of moving objects, like air, to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to Earth's rotation.

Friction between the air and Earth's surface, which further influences wind direction.

A key feature of Earth's climate system, influencing wind patterns, precipitation, and temperature distribution.
