Weather
| Question | Answer |
|---|---|
| latitude | angular distance north or south from the earth's equator measured through 90 degrees |
| longitude | angular distance measured on a great circle of reference from the intersection of the adopted zero meridian with this reference circle to the similar intersection of the meridian passing through the object |
| hemisphere | half of a spherical or roughly spherical body (such as a planet) |
| atmosphere | the whole mass of air surrounding the earth |
| weather | the state of the atmosphere with respect to heat or cold, wetness or dryness, calm or storm, clearness or cloudiness |
| climate | the average course or condition of the weather at a place usually over a period of years as exhibited by temperature, wind velocity, and precipitation |
| polar | of or relating to a geographic pole or the region around it |
| Continental | of, relating to, or characteristic of a continent |
| maritime | of, relating to, or bordering on the sea |
| Clouds | a visible mass of particles of condensed vapor (such as water or ice) suspended in the atmosphere of a planet (such as the earth) or moon |
| condensation | a chemical reaction involving union between molecules often with elimination of a simple molecule (such as water) to form a new more complex compound of often greater molecular weight |
| cirrus clouds | short, detached, hair-like clouds found at high altitudes |
| hygrometer | any of several instruments for measuring the humidity of the atmosphere |
| Map | a representation usually on a flat surface of the whole or a part of an area |
| globe | something spherical or rounded |
| Cumulonimbus (storm clouds) | cumulus cloud having a low base and often spread out in the shape of an anvil extending to great heights |
| Cirrocumulus | a high-altitude cloud form consisting of small white rounded masses usually in regular groupings |
| Stratocumulus | stratified low cumulus consisting of large balls or rolls of dark cloud which often cover the whole sky especially in winter |
| Cirrostratus | a fairly uniform high thin cloud layer darker than cirrus and often covering the entire sky |
| Nimbostratus (steady rain) | a low dark layer of gray cloud usually producing light continuous rain or snow |
| Rain | water falling in drops condensed from vapor in the atmosphere |
| freezing rain | rain that freezes upon contact with a surface (such as the ground) |
| sleet | rain that freezes or partly freezes as it falls from the sky |
| snow | precipitation in the form of small white ice crystals formed directly from the water vapor of the air at a temperature of less than 32°F (0°C) |
| Hail | precipitation in the form of small balls or lumps usually consisting of concentric layers of clear ice and compact snow |
| Rain Gauge | an instrument for measuring the quantity of precipitation |
| Wind | a natural movement of air of any velocity |
| Anemometer | an instrument for measuring and indicating the force or speed and sometimes direction of the wind |
| wind vain | an instrument that measures the direction from which the wind is blowing |
| Crayola's effect | the apparent deflection of a moving object that is the result of the Coriolis force |
| Trade winds | a wind blowing almost continually toward the equator from the northeast in the belt between the northern horse latitudes and the doldrums and from the southeast in the belt between the southern horse latitudes and the doldrums —usually used in plural |
| prevailing Westerlies | the average or normal westerly winds of the middle latitudes |
| polar Easterlies | form when the atmosphere over the poles cools |
| land breezes | a breeze blowing usually at night toward the sea from the more rapidly cooling land |
| sea breezes | a cooling breeze blowing generally in the daytime inland from the sea |
| Air pressure | : the pressure within a container due to the compression of atmospheric gases |
| Barometer | : an instrument for determining the pressure of the atmosphere and hence for assisting in forecasting weather and for determining altitude |
| low pressure | : having, exerting, or operating under a relatively small pressure |
| high pressure | having or involving a high or comparatively high pressure especially greatly exceeding that of the atmosphere |
| cold front | an advancing edge of a cold air mass |
| warm front | an advancing edge of a warm air mass |
| stationary front | the boundary between two air masses neither of which is replacing the other |
| air mass | a body of air extending hundreds or thousands of miles horizontally and sometimes as high as the stratosphere and maintaining as it travels nearly uniform conditions of temperature and humidity at any given level |
| El Nino | an irregularly recurring flow of unusually warm surface waters from the Pacific Ocean toward and along the western coast of South America that prevents upwelling of nutrient-rich cold deep water and that disrupts typical regional and global weather patter |
