Concept of pressure Pressure is the perpendicular force per unit area, or the Stress at a point within a confined fluid. The pressure exerted on a floor by a 42-pound box the bottom of which has an area of 84 square inches is equal to the force divided by the area over which … Read more
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 … Read more

SDO is a NASA mission launched on February 11, 2010 which will observe the sun for over five years. The observatory is a part of the living with a star program. SDO’s goal is to understand the sun’s influence on earth and near-earth space by studying the solar Atmosphere on small scales of space and … Read more
The following are subtopics of tertiary winds: Katabatic winds are cold, dense winds that flow downslope under the force of gravity. They are most common in mountainous regions, where they can reach speeds of up to 100 miles per hour. FoehnFoehn winds are warm, dry winds that descend from mountains after being forced to rise … Read more
The following are subtopics of Westerlies: Definition: The prevailing westerlies are the prevailing winds in the middle latitudes that blow from the west to the east in the Northern and Southern Hemispheres. Cause: The prevailing westerlies are caused by the Earth’s rotation and the difference in temperature between the equator and the poles. Effects: The … Read more
