Wind Review
Local and Global Winds
| Question | Answer |
|---|---|
| The horizontal movement of air from an area of high pressure to an area of low pressure is referred to as | wind |
| The polar easterlies blows from the __________ and to the ____________. | from the east to the west |
| The prevailing westerlies blows from the __________ and to the ____________. | from the west to the east |
| A wind (weather) vane measures | wind direction |
| Winds over short distances are called | local winds |
| Winds that blow in the same direction over long distances are called | global winds |
| Both winds are caused by the | unequal heating of Earth by the SUN (which causes differences in air pressure). The air pressure moves from high to low. |
| What causes the winds to curve, instead of going straight? | The rotation of Earth under the wind. This is called the Coriolis Effect |
| What are the calm (wind) areas of Earth called? | Horse Latitude and Doldrums |
| Where are the Doldrums located? | equator |
| Whare are the horse latitudes located? | 30 degrees North and 30 degrees South |
| Why are the doldrums clam (very little to no wind)? | The equator receives direct sunlight, which causes the air to be warm, less dense, and rise. All of the air is rising. |
| Why are the horse latitudes calm (very little to no wind)? | The 30 degree latitudes are cold, high density, sinking air. All of the air is sinking. |
| How are winds named? | From the direction they are coming from |
| Where would the lowest air pressure be on Earth? Why? | The equator because it gets the most direct sunlight |
| Where would be the highest air pressure be on Earth? Why? | The North and South Poles because it gets the most indirect sunlight |
| What is a land breeze? | happens during the night this is when cool air is above the land creating a high pressure and warm air is above the sea creating low pressure then the air moves from the land to the sea creating a land breeze |
| What is a sea breeze? | happens during the day this is when cool air is above the sea creating a high pressure and warm air is above the land creating low pressure then the air moves from the sea to the land creating a sea breeze |
| What is an instrument that measures the wind speed called? | anemometer |
| What is an insturment that shows the direction the wind is blowing called? | wind vane |
