Right the correct letter to the left of the word. 14. __________ Wind A. Happens at night. The land cools down faster than the water. The cool air over the land sinks (high pressure) and the warm air over the water rises (low pressure). This causes the cool air to blow from the land out to the water. 15. __________ Coriolis Effect B. An arrow that swings to point into the direction of the wind. 16. __________ Prevailing Westerlies C. (30 degrees N and S). Warm air from the equator moves both North and South. Around 30 degrees North and South, the air stops moving towards the poles and sinks, causing a belt of calm air. 17. __________ Wind Vane D. Has “cup-­‐like” devices which are mounted to an axle. The force of the winds pushes the cups, which turns the axle, which records wind speed. 18. __________ Land Breeze E. Happens during the day. The land heats up faster than the water. The warm air over the land rises (low pressure), and the cool air over the water sinks (high pressure). This causes the cool air to blow inland from the water. 19.__________ Doldrums F. Since Earth rotates, global winds do not follow a straight path from the poles to the equator like they otherwise would. As the winds blow, the Earth rotates underneath, making the winds have a curved path. (IT IS REALLY THE EARTH WHICH IS CURVING THE WINDS). This causes the global winds in the NORTH to turn to the RIGHT, and in the SOUTH turn in to the LEFT. 20. __________ Trade Winds G. (0-­‐30 degrees N and S). When the cold air from the horse latitudes sinks, it creates High Pressure. Northern Hemisphere = Blow from the NE. Southern Hemisphere = Blow from the SE. 21. __________ Polar Easterlies H. (60 -­‐ 90 degrees N and S). Cold air near the poles sinks and flows to the warmer, lower latitudes. They blow in cycles, and create Polar Fronts when they meet the prevailing Westerlies. 22. __________ Anemometer I. The horizontal movement of air from a place of high pressure to a place of low pressure. The unequal heating of the atmosphere causes these differences in air pressure, which creates wind. 23. ________ Horse Latitudes J. (60 -­‐ 90 degrees N and S). Cold air near the poles sinks and flows to the warmer, lower latitudes. They blow in cycles, and create Polar Fronts when they meet the prevailing Westerlies. 24. ________ Humidity K. (O degrees). Found at the equator. Warm air rises, and cool air moves into the area. However, since the air is so quickly warmed it doesn't move very far = very weak or no winds. 25. ________ Sea Breeze L. The measure of the amount of water vapor in the air. Depends on temperature -­‐ warm air can hold more water. 26. ________ Polar Easterlies M. (30 -­‐ 60 degrees N and S). The remaining bit of warm air from the horse latitudes rises and moves towards the poles. Northern Hemisphere = Blow from the SW. Southern Hemisphere = Blow from the NW.
