PPT-2. Atmospheric pressure Molecular view of atmospheric pressure

EARTH SURFACE gravity random motion Weight of all air molecules is propagated to surface by random motion of molecules Random motion of molecules causes pressure to be applied in all directions. Atmospheric Pressure and Surface Salinitywww.aoml.noaa.gov/phod/dac/gdp.html Spherical surface floatOther Sensors that can be added: (sea anchor) The satellite-tracked drifter The Global Drifter Array . By . Ruchita. . Aggarwal. . Meteorologist . A meteorologist is a person who studies meteorology. Meteorology is the study of the changes in temperature, air pressure, moisture, and wind direction in the troposphere. It is basically the science of the atmosphere. It gives us the basic idea of the forces that cause weather and climate. As well as how human activities can affect climate, for example pollutants in the atmosphere.
