What is the ITCZ
These are belts of high pressure located around 30 degrees latitude in both the Northern and Southern Hemispheres.
These are low-pressure belts located around 60 degrees latitude in both hemispheres. They are regions of rising air and are associated with stormy weather and precipitation.
an area near the equator where the trade winds from both hemispheres converge. It is characterized by low pressure and a band of clouds and thunderstorms.
These are belts of high pressure located near the poles. The air at these latitudes is cold and dense, leading to sinking air and stable conditions.
what 2 things does the ITCZ impact? and how?
Semi-permanent Pockets of Pressure:
influences the paths of storm systems and can bring unsettled weather conditions to higher latitudes
a high-altitude, fast-flowing, narrow air current that flows near the boundaries between cold polar air and warmer air from lower latitudes.
acts as a boundary between different air masses, and its meandering path influences the movement and intensity of weather systems.
regions of somewhat stable atmospheric pressure found in certain areas of the world,. Their positions remain more or less consistent throughout the year.
