| Question | Answer |
|---|---|
| What occurs because of the uneven way the sun heats the earth, sun heats the equator more than it does any other part of the earth giving the equator a lower density and lower pressure. | Global Winds |
| What is a large body of air covering hundreds of thousands of square kilometers that has a relatively uniform temperature and humidity. | Air Mass |
| What, in meteorology, is a region with relatively uniform temperature and humidity over which air masses form. | Source Region |
| What is an air mass that is warmer than the surface over which it moves. | Warm Air Mass |
| What is an air mass that is colder than the surface over which it moves. | Cold Air Mass |
| What is the boundary surface between two dissimilar air masses. | Front |
| What is a zone of contact between two dissimilar air masses where neither is advancing. It usually results in no change in weather for several days. | Stationary Front |
| What is a front formed when a cool air mass and a rapidly moving cold air mass traps a warm air mass between them. The warm air mass is lifted, losing all contact with the ground. | Occluded Front |
| What is movement of air from a place of high pressure to a place of low pressure. | Wind |
| What is a regional wind system that reverses periodically, alternately bringing wet and dry seasons. | Monsoon |
| What is the heat or light emitted by a glowing object. Also, the particles and rays emitted by a radioactive material. | Radiation |
| What is the direct transfer of thermal energy through a substance or from one object in physical contact with another. | Conduction |
| What is the indirect transfer of thermal energy from one place to another by the movement of currents of cooler, more dense matter into regions of warmer, less dense matter. THIS occurs in liquids and gases because their particles are mobile. | Convection |
| What is a device for indicating wind direction. | Wind Vane |
| What is an instrument for measuring wind speed using cupped scoops mounted on a rotating shaft. | Anemometer |
| What is the horizontal force exerted on a mass of air that has a higher pressure on one side than on the other. | Pressure gradient force |
| What is a high-altitude wind that is controlled by the relative influence of the pressure gradient force and the Coriolis effect. | Geostrophic wind |
| What is a weather system centered on a low-pressure area surrounded by a wind circulation pattern spiraling counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. | Cyclone |
| What is an area of relatively higher atmospheric pressure. It typically contains a clockwise-rotating wind system in the Northern Hemisphere. Highest pressure center. | Anticyclone |
| What is a high-speed meandering wind current that is usually flowing from west to east at altitudes of 15 to 25km. Its speed often exceeds 400 km/h. | Jet Stream |
| What is a breeze that blows onshore from ocean, usually happens during the daytime, 3 letters-day 3 letters-sea | Sea breeze |
| What is a breeze that blows from shore to water and it usually happens at night, 4 letters-land, 4 letters-dark | Land breeze |
| What is a breeze that blows up the mountainside from the valley when air high on the mountain heats and rises. It usually occurs late in the day. | Valley breeze |
| What is a breeze that flows down the mountain into the valley at night. | Mountain breeze |
| What is consistent winds extending from the subtropical highs toward the equator, turned by the Coriolis effect into easterlies. They were formerly used by sailing ships to go from Europe to North and South America. | Trade Winds |
| What are winds blowing consistently from southwest to northeast between 30 degrees and 60 degrees north and south latitudes. Wind that affect the U.S. This is why weather comes to us from the west and blows east. | Prevailing westerlies |
| What is North and South of 60 degrees latitudes, and shifts winds toward the west coming from the east. It BLOWS AWAY FROM THE POLES. | Polar easterlies |
| What is a permanent low-pressure belt of usually windless air near the equator caused by the vertical rising of warm air. | Doldrums |
| What are bands of nearly permanent high pressure at approximately 30 degrees north or south latitude caused by descending cold air. Named because sailing ships that drifted for weeks in these were forced to eliminate cargoes of livestock when watr ws shrt | Horse latitudes |
| What is a prevailing low-pressure belt at approximately 60 degrees north or south latitude. In the Northern Hemisphere the prevailing westerlies rise above the polar easterlies, lifting air in this zone. | Subpolar low |
| What is an area of high atmospheric pressure at either pole caused by subsiding cold air. | Polar highs |
