Question
b. The air parcel will continue traveling towards the east at 5 m/s C. The air parcel will travel towards the west at 5 m/s 3. Which of the following is FALSE? The pressure gradient force exists if there is a difference in pressure over a given distance. The pressure gradient force points towards areas of high pressure. The pressure gradient force is the force that creates the wind. a- b. C. Why do scientists use the concept of equivalent sea-level pressure? a. To account for differences in elevation. b. Because all the important weather occurs at sea-level. c. Scientists do not use the concept of equivalent sea-level pressure, instead scientists only use surface pressures 5. True/False: A warm column of air is associated with low pressure aloft and rising motion? a. True b. FalseExplanation / Answer
3. The pressure gradient force points towards areas of high pressure. Because pressure gradient force is the force which creates the winds when there is a difference in pressure across a surface. The air moves from the higher pressure to lower pressure area.
4. Scientists use the concept of equivalent sea-level pressure to account for differences in elevation. Because the air pressure decreases with increasing elevation above sea level and increases below the sea level. So, to measure elevation equivalent sea-level pressure of mean sea-level pressure has been used.
5. A warm column of air is associated with low pressure aloft and rising motion is true. Because warm air become lighter and density decreases. So, it moves upward.
