weather
| Question | Answer |
|---|---|
| weather | the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure, etc. |
| atmosphere | the gaseous envelope surrounding the earth; the air. |
| ozone | In the upper atmosphere, it absorbs ultraviolet rays, thereby preventing them from reaching the surface of the earth. |
| water vapor | Water vapor or is the gas phase of water |
| photo chemical smog | Fog that has become polluted with smoke and particulates, especially from burning coal |
| Acid Rain | rain or other precipitation with a high concentration of acids |
| Pressure | a pressing or being pressed; compression; squeezing |
| Air Pressure | the pressure of atmospheric or compressed air |
| Barometer | an instrument for measuring atmospheric pressure |
| Mercury Barometer | barometer that shows pressure by the height of a column of mercury |
| Aneroid Barometer | a barometer with a needle connected by mechanical linkages and springs to a thin, hollow metal disk in which a partial vacuum is maintained: a change in atmospheric pressure changes the shape of the disk, thus moving the needle |
| Altitude | height, elevation, loftiness, eminence |
| Jet Stream | any of several bands of high-velocity winds moving from west to east around the earth |
| Troposphere | The lowest and densest region of the Earth's atmosphere |
| Stratosphere | the atmospheric zone or shell located above the tropopause |
| Mesosphere | The region of the earth's atmosphere above the stratosphere and below the thermosphere. |
| Thermosphere | The region of the atmosphere above the mesosphere |
| Lonosphere | The layer of the earth's atmosphere that contains a high concentration of ions and free electrons |
| Exosphere | The outermost region of a planet's atmosphere. |
| Electromagnet Wave | electromagnetic radiation: radiation consisting of waves of energy associated with electric and magnetic fields |
| Radiation | The emission of energy as electromagnetic waves or as moving subatomic particles |
| Infrared radiation | electromagnetic radiation with wavelengths between those of visible red light and radio waves |
| ultraviolet radiation | radiation lying in the ultraviolet range; wave lengths shorter than light but longer than X rays |
| Scattering | A small, dispersed amount of something |
| Thermal energy | the form of energy that is created by heat |
| Conduction | The process by which heat or electricity is directly transmitted through a substance |
| Convection | The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise |
| Wind | The perceptible natural movement of the airin the form of a current of air blowing from a particular direction |
| Anemometer | An instrument for measuring the speed of the wind, or of any current of gas |
| Wind-chill factor | the felt air temperature on exposed skin due to wind |
| local wind | Winds that are generated over a comparatively small area by local terrain and weather |
| Sea breeze | A breeze blowing toward the land from the sea |
| Land Breeze | A breeze blowing toward the sea from the land |
| Global wind | the large-scale movement of air |
| Latitude | Regions, esp. with reference to their temperature and distance from the equator. |
