Atmospheric pressure forces mercury to rise in the tube. At stations near sea level, the column of mercury rises on the average to a height of 29.92 in. In other words, a column of mercury of that height weighs the same as a column of air having the same cross section as the column ...

D. As the body goes deep into sleep and the nervous system begins to be quiet, blood pressure and heart rate drop and this change can cause a falling dream. O’Connor says that dreaming about falling is the mind’s way of warning the dreamer of a situation in his or her waking life...
...lbs.) as the sine of 13 degrees is to the cosine of 13 degrees, or (.22 x 108) / .97 24 lbs.; but this slightly exceeds the total pull of 23 lbs. on our scales. Therefore, it is evident that theaveragepressure on the surface, instead of being normal to the chord, was ...
Numerous factors play a role in this sea level rise, scientists found, including those that are both natural and human-made. Study co-author Noah Hendricks said that they looked at those causes, including vertical land motion, ice-mass loss and air pressure, but that "none of them could su...

In determining the atmospheric status of the tropical Pacific, climatologists devised the Southern Oscillation Index (SOI, Figure 3). It is the standardized sea level pressure difference between Darwin, Australia, and Tahiti, French Polynesia, in the central Pacific (Tahiti minus Darwin). Thus, when...
Precipitation is scarce and is concentrated in summer, when the country is partly affected by the Asian monsoon; in winter, when a thermal high pressure system dominates, the sky is often clear. Precipitation is more abundant in the north, where it exceeds 300 millimeters (12 inches) per year...
