Marano Weather 5

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
