Halley’s theory, suggested in 1686, considers the summer monsoon to be a regional phenomenon. Aerological concept: This was suggested by R. Scherhag in … 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 of mercury … Read more
