The North American monsoon is generated by the seasonal wind shifts associated with: - Answer-the development of a summertime thermal low in Arizona. What are Rossby waves? - Answer-wave patterns in the upper level westerlies and polar jet stream El Niño events are characterized by: - Answer-pooling of unusually warm water in the eastern tropical Pacific. The Southern Oscillation: - Answer-is a cycle of strengthening and reversing trade winds in the equatorial Pacific. Land-sea breezes and ________ are mesoscale winds. - Answer-chinooks The __________ travel(s) from the subtropical high to the Equator. - Answer-trade winds Define a Hadley cell. - Answer-A three-dimensional tropic circulation cell where air rises at the Equator and sinks at ~30o latitude Subsiding cold air at the polar high produces the __________. - Answer-polar easterlies What two pressure zones in the Northern Hemisphere are connected by the westerly winds? - Answer-Subtropical high and polar front The intertropical convergence zone (ITCZ) is characterized by __________. - Answer-warm, moist air that rises and travels both North and South An air mass is a body of air with: - Answer-similar values of temperature and moisture at any given altitude. Air masses are identified by a pair of letters, one lowercase and one uppercase. The uppercase letter (P, A, or T) refers to: - Answer-the approximate latitude of the air mass source region. An ideal source region of air masses should be: - Answer-physically uniform. An air mass is often modified as it moves over the earth's surface. This modification is largely due to: - Answer-contact with the new surface below.
