ATOC Exam 2 Questions with Correct Answers Latest Update Surface air is warmer and drier as a result of compressional heating in a downslope wind. true or false - Answers True An altimeter is often just an aneroid barometer that has been calibrated to indicate altitude. T or F - Answers True Clouds, fogs, and precipitation are more likely to form where prevailing winds are upslope than where the winds are downslope. T or F? - Answers True Cumulus cloud formation above a mountain in the early afternoon could indicate a well-developed valley breeze. T or F? - Answers True The polar jet stream is strongest in the winter when surface temperature contrasts are greatest. T or F? - Answers True The Coriolis force is the force that causes the wind to blow. T or F? - Answers False Two parcels of air with the same volume and temperature will also always have the same pressure. T or F? - Answers False A warm northward flowing ocean current is found along the east coast of the United States and a cold southward moving current is found along the west coast. T or F? - Answers True Upper-level winds blow from west to east in both the Northern and Southern Hemispheres. T or F? - Answers True Surface winds and upper-level winds blow in the same direction in a thermal circulation.
