Weather
| Term | Definition |
|---|---|
| Latitude | Geographic coordinate that specifies the north or south of the equator |
| Longitude | distance measured in degrees east or west from an imaginary line (called prime meridian) that goes from the North Pole to the South Pole and that passes through Greenwhich, England |
| Hemisphere | The half of Earth, divided by a imaginary line dividing the earth into the Northern and Southern hemisphere, or eastern and western hemisphere |
| Atmosphere | The atmosphere is a layer of gas and suspended solids extending from the Earth's surface up many thousands of miles, becoming increasingly thinner with distance but always held by the Earth's gravitational pull. |
| Weather | The state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, |
| Climate | The weather conditions present in an area in general or over a long period. |
| Rain | Precipitation |
| Freezing rain | rain that freezes on impact with the ground or solid objects. |
| Sleet | a form of precipitation consisting of ice pellets, often mixed with rain or snow. |
| Snow | atmospheric water vapor frozen into ice crystals and falling in light white flakes or lying on the ground as a white layer. |
| Hail | chunks of ice fall from the sky |
| Rain Gauge | a device for collecting and measuring the amount of rain which falls. |
| Wind | the movement of air from high pressure to low pressure |
| Anemometer | A weather instrument hat measures wind speed |
| Wind Vane | An instrument that measures the direction from which the wind is blowing |
| Coriolis Effect | a force that affects a moving object over a rotating body. |
| Trade winds | a wind blowing almost constantly toward the equator from an easterly direction. |
| Prevailing Westerlies | These winds blow from the west and are located at mid latitudes of the Earth |
| Polar Easterlies | form when the atmosphere over the poles cools. |
| Land Breeze | a breeze blowing toward the sea from the land, especially at night, owing to the relative warmth of the sea. |
| Sea Breeze | a breeze blowing toward the land from the sea, especially at daytime, owing to the relative cooling of the sea. |
| Air pressure | the weight of the air pushing everything around you |
| Barometer | a weather instrument that measures air pressure |
| High pressure | Brings good, fair weather, sunny and clear skies caused by a rise in air pressure |
| Low Pressure | Brings heavy and bad weather caused by a drop in air pressure |
| occluded front | Formed where a slower moving warm front is followed by a more rapidly moving cold front. Cold fronts overtake the warm fronts, 2 fronts continue to move tandem (together). Lots of varieties of weather, but usually status clouds or light precipitation. |
| stationary front | A boundary between 2 different air masses, neither of which is strong enough to replace the other. They bring clouds and prolonged precipitation. :weather maps with red/or blue line of half circles and triangles pointing in opposite directions. |
