A dangerous weather phenomenon called a bomb cyclone that occurs in mid-latitudes - between Earth's tropics and the polar ...

Why? Because of the many factors which affect atmospheric pressure. Pioneering scientists discovered atmospheric pressure (also known as barometric or air pressure) in the 17th century ...

The deepest point of the ocean is believed to be the Challenger Deep in the western Pacific, which is deeper than Mount ...

A historically strong storm system with the strength of a hurricane whipped damaging winds through the Pacific Northwest ...

Air molecules colliding with a surface cause atmospheric pressure. Atmospheric pressure at sea level is about 101,000 Pa (101 kPa) but just 27,000 Pa (27 kPa) at the cruising altitude of a ...

Zero elevation is defined as the isobar where the atmospheric pressure is equal to 610.5 Pa (for reference, “sea level” on earth has an atmospheric pressure of 101.5 kPa). Though seemingly ...

Pressure is measured in millibars. Standard pressure at sea level is 1013 millibars, but large areas of either high or low pressure can occur. Areas of high and low pressure are caused by rising ...
