Pressure and wind belts Atmospheric Pressure, also called barometric pressure, force per unit area exerted by an atmospheric column (that is, the entire body of air above the specified area). Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure), which indicates the height of a column of mercury … Read more
The Northeast Trade Winds: A Vital Force Shaping Weather and Climate The Northeast Trade Winds, a consistent and powerful wind system that blows from the northeast towards the equator, are a defining feature of the global atmospheric circulation. These winds play a crucial role in shaping weather patterns, influencing ocean currents, and impacting ecosystems across … Read more
The Southeast Trade Winds: A Vital Force Shaping Weather and Climate The Southeast Trade Winds, a consistent and powerful wind system blowing from the southeast towards the equator, play a crucial role in shaping weather patterns and influencing global climate. These winds, along with their counterparts in the Northern Hemisphere, the Northeast Trade Winds, form … Read more
