Pressure gradient force (PGF) - Answer Directed from higher towards lower pressure at right angles to the isobars; force th...

WX 201 Exam 3 HW #1 & 2 Questions and Answers Upper-level winds in the middle latitudes of both hemispheres generally blow from ____. - Answer-The west The pressure gradient force is directed from higher pressure toward lower pressure - Answer-at all places on Earth. The Coriolis force acts at a ____ degree angle to the wind. - Answer-90 On a 500 millibar chart, ____ are drawn to represent horizontal changes in altitude which correspond to horizontal changes in pressure. - Answer-Con...

One way to change air pressure is to.. - ANSWER-move up or down in the atmosphere Pressure decreases with.. - ANSWER-height Can a plane door really be opened while in flight? - ANSWER-Cant open the door, they open in first and then open out Air pressure outside of the plane is very low, the cabin pressure is much greater Adding cold air to an air column will.. - ANSWER-shorten the column Adding warm air to an air column will.. - ANSWER-expand/make the air column taller Horizont...

WX 201 Exam 2 Questions with Correct Answers Isobaric (constant pressure) surface - Answer-• Constant pressure at all points (altitude varies) • Higher (lower) heights form over warm (cold) air • High (low) heights correspond to regions of high (low) pressure • Stronger height gradient Þ stronger wind • Winds parallel to height contours (geostrophic) Sources of vertical motion - Answer-· May generate precipitation o 1. Convergence/divergence o 2. Orography (topography) o 3...

WX 201 Exam 3 with correct Answers The contour lines drawn on a 500 mb chart are lines of constant height The unit of pressure most commonly found on a surface weather map is millibars or hectopascals Isobaric surfaces are ____ in warm, less-dense air and ____in cold, more-dense air. higher; lower Because of friction, surface winds move ____ winds aloft with the same pressure gradient. more slowly than The pressure gradient force is directed from higher pressure toward l...

WX 201 Exam 3 HW #1 & 2 Questions and Answers To correctly monitor horizontal changes in air pressure, the most important correction for a mercury barometer is the correction for - Answer-altitude A geostrophic wind is a wind that results from a balance between the ____ force and the ____ force. - Answer-Coriolis; pressure gradient There is always a strong pressure gradient force directed _________. - Answer-upward If, at your home in the Northern Hemisphere, the surface wind is blow...

3 states of water solid- ice gas- vapor liquid- water evaporation Liquid to gas sublimation solid to gas deposition gas to solid condensation Gas to liquid when latent heat is reduced and stored latent heat is transferred when water changes state -release of energy occurs when HEATING -absorption of energy occurs when COOLING hydrosphere (volume) The total water realm of the earth's surface including the oceans (97.5%) and freshwater (2.5%) ...

Atmospheric Charts - Answer-• Contours: - Isobars or height contours (solid), - isotherms (long dash), or - isotachs (short-dash) • Include station models at given stations • Lows, highs, troughs, ridges, fronts Isobaric charts - Answer-• Acquire weather balloon (radiosonde), satellite, & aircraft data from many stations at the same time - Create maps of height and temperature for a given constant pressure surface • Standard pressure levels selected: 850, 700, 500, 300, and 2...

IPS1501 Assignment 4 Year Module (Due: 28 August 2023) Which of the following conditions would lead to a motion that is NOT geostrophic flow? a. motion near the surface b. being in the Southern Hemisphere c. straight, parallel isobars d. Pressure gradient force cancels the Coriolis force e. the absence of friction For geostrophic flow the wind moves parallel to the isobars with the lower pressures on the _____ if you are looking in the direction the wind is blowing toward. Which wind f...
