Marano Weather 5
| Question | Answer |
|---|---|
| meteorologist | scientist who forecasts weather |
| synoptic weather forecasting | looking at synopsis (summary) of weather variables at specific time at several locations |
| Station model | symbols using in synoptic weather maps |
| In a station model, temperature is recorded in ____ | Fahrenheit |
| In a station model, visibility is recorded in ____ | miles |
| In a station model, dew point is recorded in ____ | Fahrenheit |
| In a station model, barometric pressure is recorded in ____ | mb- only the last three numbers |
| In a station model, precipitation is recorded in ____ | how many inches in the last three hours |
| Field on field map | a region of space that has a measurable quantity at every point |
| isolines | lines that connect all point of equal value on a map |
| isotherms | isolines for temperature |
| isobars | isolines for pressure |
| The closer the isobars, the (weaker, stronger) the winds | stronger |
| thunderstorm begins as a ___________ | convection cell (warm air rises, expands, cools and sinks) |
| lightning | air gets heavy, rain begins to fall and causes friction with the air moving upward |
| lightning-definition | large electrical discharge that occurs between two oppositely charged surfaces |
| The upper part of the cloud carries (negative, positive) charge while lower part is (negatively, positively) charged | positive, negatively |
| Tornadoes | small brief disturbances that develop over land from an intense thunderstorm |
| tornadoes result because of | warm air that is forced upward and causes a sharp decrease in air pressure. Form over water near Equator during summer months. |
| Hurricanes occur when | air over warm oceans is heated, pressure decreases. |
| Wind speed of hurricanes | 119 km/hr |
| Climate | the average conditions in an area over a long period of time |
| climate is determined by _____ and _____ | temperature and precipitation |
| Other factors that influence climate are | latitude, wind patterns, geography, and ocean currents |
| Latitude | the distance north or south measured in degrees from the equator |
| The higher the latitude, the _____ the climate | cooler |
| When does summer solstice occur? | June 21 |
| When does the autumnal equinox occur? | Sept. 21-23 |
| When does the winter solstice occur? | Dec. 21 |
| When does the vernal equinox occur? | Mar. 21-23 |
| Prevailing winds | winds that blow mainly from one direction |
| Prevailing winds influence _____ and _____. | moisture and temperature |
| Elevation | height of surface landforms above sea level |
| As elevation (increases, decreases) the atmosphere becomes less dense, less able to hold heat (cooler) | increases |
| Three major climate zones based on latitude | tropical, temperate, and polar |
| biome | large region characterized by a specific type of climate and plants and animals that live there |
| tropical zone | warm zone located around the equator, extends from the Tropic of Cancer to Tropic of Capricorn |
| Tropical rainforest | warm and wet |
| Tropical desert | less than 25 inches rainfall per year |
| Tropical savannas | grasslands with warm, dry season |
| Temperate zone | between the Tropics and Polar zone |
| Temperate forests | large amounts of rain, seasonal temperature differences |
| Temperate grasslands | prairies, steppes, veldt, pampas- too little rainfall for trees to grow, seasonal temperatures, most fertile soil of all biomes |
| Chapparals | cool, wet winters and hot, dry summers, very rocky |
| Temperate desert | cold desert located in rain shadow of mountain |
| Polar zone | coldest average temperature |
| tundra | very dry, 24 hours of daylight of darkness |
| permafrost | permanently frozen layer of soil, water cannot drain |
| taiga | long cold winters and short warm summer |
| microclimate | small regions with unique climate characteristics |
