Topic 7:Weather B

Atmospheric Pressure & Density, pgs. (128-130)

QuestionAnswer
Define pressure: Force per given amount of area; such as pounds per square inch.
Define air pressure or barometric pressure: The weight of the overlying atmosphere pushing down on a given area.
Name the instrument used to determine air pressure. A barometer.
State the two commonly employed units of air pressure. Millibars, and inches. (see figure 7-2, page 129)
List one average atmosphere's worth of air pressure in millibars, inches, and pounds per square inch. See page 13, ESRT; 1013.2 mb, 29.92 inches, and 14.7 lbs./in2
Name the isolines that connect adjacent points of equal air pressure. Isobars.
Describe the effect of air temperature upon air pressure. Inverse relationship. As temp. increases, the pressure decreases; due to lower density, lighter air - which will rise.
Describe the effect of humidity or water vapor upon air pressure. Inverse relationship. The greater the humidity, or greater the vapor pressure, the lighter the air mass is resulting in lower air pressure. (H2O is lighter than N2 or O2!!!)
Discuss the impact of an increase in altitude upon air pressure. Inverse relationship. As altitude increases, air pressure decreases. There is less gas above your head as one rises/climbs towards outer space.
How does one convert 30.53 inches into millibars? ESRT pg. 13, = 1034.0 mb
Abbreviate 1034.0 millibars as it would be shown on a Station Model. 340
Explode the abbreviated Station Model air pressure readings of 005, & 856. 1000.5 mb, and 985.6 mb.
Can you answer the multiple choice questions found on page 130, (8-17)? Please place answers in your Regents Review Book.
