Meteorology Flashcards
The study of the earth’s atmosphere is called,
Meteorology
Branch of meteorology that deals w/ the state of the atmosphere averaged over a long period of time
Climatology
Atmospheric condition over a short duration, particularly the combination of heat, moisture & wind characteristics of the atmosphere in a day
Weather
The total weather condition of an area as generalized over a long period of time, (seasons, years, decades)
Climate
KINDS OF CLIMATE
Macroclimate, Mesoclimate, Microclimate
A kind of climate that prevail over a large region of the earth’s surface
Macroclimate
A kind of climate where areas up to several square miles
Mesoclimate
A kind of climate that over short distances, or within few feet or inches
Microclimate
Assumes that climate is brought by the difference in temp. & angles of the sun’s rays at diff. loc
According to Geographic Zones, Greek Philosopher Parminedes
Between the tropic of cancer (23.5°N) & tropic of capricorn (23.5°S)
Torrid Zone
Between the tropics and polar circles (66.5°N and S)
North and South Temperate Zones
Between the polar circles and poles
North and South Frigid Zones
The most widely used system for classifying the world’s climates (German Meteorologist Vladimir Peter Koppen)
Koppen Classification System
Northward & Southward from the equator (15-20deg of Lat), Ave. temp. >18degC, Annual precipitation is >1500 mm
Tropical Moist Climate (A)
Climates extends from 20-35degN and S of the equator
Dry Climates (B)
Warm & humid summers w/ mild winters, from 30-50deg of lat, estern & western borders
Moist Tropical Mid-Latitude Climates (C)
Warm to cool summers & cold winters. Ave. temp warmest mos >10degC, coldest mos <-3degC
Moist Continental Mid-Latitude Climates (D)
Year-round cold temp w/ warmest mos <10degC
Polar Climates (E)
Ice cop, subpolar
Cold Climates
Subarctic, Humid continental (short summer), Humid continental (long summer)
Cold Temperate Climate
Temperate marine, Humid Subtropical, Dry Summer Subtropical
Warm Temperate Climate
Arid Mid-latitude, arid low-latitude, semi-arid mid latitude, Semi-arid low latitude
Dry Climates
Rainy and dry tropical, Rainy tropical, Highlands
Tropical Climates
treeless plain, mosses, low-lying plants
Tundra
coniferous forests
Taiga
treeless plain, dry and grass - covered
Steppe
two pronounced wet & dry season, wet (june-nov), dry (dec-may)
Type I
no dry season, w/ a pronounced max rain (dec-feb)
Type II
intermediate type w/ no pronounced max rain & short dry season (one-three months)
Type III
uniformly distributed rainfall
Type IV
MAJOR FACTORS AFFECTING TERRESTRIAL CLIMATTE
Position of the Earth, Land & Water Masses, Surface Features of the Land, Wind Systems & Pressure Belts, Ocean Currents & Drifts
The earth’s declination, rotation, and revolution affects incoming radiation, land temperature, length of day and night and tides.
Position of the Earth
The geographic distribution of continents and ocean affect regional temperature, precipitation, wind direction and speed.
Land and Water Masses
The large-scale mountainous features of land masses, i.e. altitude, depressions, mountain ranges and other geographic features.
Surface Features of the Land
The general circulation of the atmosphere affects pressure in the atmosphere and land and water masses, and the development of weather disturbances.
Wind Systems and Pressure Belts
Influenced by Coriolis Effect and configuration of oceans, basin, and shorelines.
Ocean Currents and Drifts
Inertial force that acts on objects in motion w/in a frame of reference that rotates w/ respect to an inertial frame.
Coriolis Effect
Incoming sunlight
Insolation
