polar easterlies
The descent of dry air at these latitudes.
They aren't. Hurricanes are tropical systems that develop where fronts do not have as much influence as in temperate climates. A hurricane that moves into temperate latitudes can change into a frontal low, but this is not an inherent characteristic of hurricanes.
Most weather systems in the temperate latitudes move from west to east. This makes the west side of a system the trailing side. In the northern hemisphere, high-pressure systems rotate clockwise, resulting in southerly winds on the west (trailing) side.
Air moves from high pressure systems toward low pressure systems. This movement is the cause for the winds.
Global winds and pressure systems exist at the surface and at high altitudes. Surface winds include trade winds, westerlies, and polar easterlies. High altitude winds include high speed winds (which are often called jet streams). These high speed winds blow from the east in the low latitudes and from the west in the middle and high latitudes. Although local and seasonal variations occur, the wind and pressure patterns are generally predictable on the global scale. The high altitude wind and surface wind motions are related to each other.

A. Pressure systems determine where the wind blows, and while geography can affect those pressure systems it will not always affect it in the same way.
High-pressure systems in these regions prevent the formation of clouds that could carry water.

Atmospheric pressure systems are made of air.
A Low Pressure system. High pressure systems exist "by default"; meaning that high pressure systems occur everywhere that there are no low pressure systems.
Most storm systems are low pressure systems. A low pressure system draws air inward and upward at and near ground level. This can lead to the development of storms. Low pressure systems in the middle latitudes often produce fronts, which can act as wedges that lift air upward to form storms. These fronts often form troughs, or elongated areas of low pressure.
