Module 1C Flashcards
electromagnetic radiation emitted by the sun
Solar Radiation
rate of which radiation reaches the upper limits of earth’s atmosphere
Solar Constant
Solar Constant value
1,374 W/m^2
Solar radiation have ____________ wavelengths
short
Terrestrial radiation have ___________ wavelengths
Long
percent of the incoming solar radiation that is reflected from a surface
Albedo
It is when the sun is farthest from the earth
Aphelion
when the sun is nearest from the earth
Perihelion
it is when the sun’s apparent path is displaced farthest north or south
Solstice
it is when the sun passes directly over the equator
Equinox
This occur because the tilt of the Earth’s axis keeps a constant as the Earth revolves around the sun
Seasons
Weather becomes stormy when air pressure _________
air pressure falls
Weather becomes fair when air pressure _________
rises
instrument used to measure pressure
Barometer
amount of heat energy possessed by an object
Temperature
Amount of water vapor in the air
Humidity
atmospheric parameters that states air would rise near the equator and travel in the upper atmosphere towards the poles then cool and return to the equator
Hadley Circulation
Atmospheric Parameters that state it produces the change in wind direction towards the equator
Coriolis Effect
Atmospheric Circulation when heated air ascends to the equator, towards the pole at upper levels, loses heat and descend at latitude 30 degress at the ground
Tropical Cell
Atmospheric circulation which air flows towards the pole and producing westerly air flow in the mid latitudes
Middle Cell
Atmospheric Circulation where air rises 60 degress and flows toward the pole, cools and flows back
Polar Cell
Type of climate in a region where it is dry only during november - april and wet the rest of the year
Type I
Type of climate in a region where there is no dry season
Type II
type of climate in a region where dry season only last from 1-3 months
Type III
type of climate where rainfall is more or less throughout the year
Type IV
a belt of low pressure generally near the equator where trade winds come together
ITCZ
General Term for a weather system which winds rotate inward to an area of low pressure
Cyclone
rotation direction of a cyclone in the northern hemisphere
Counterclockwise direction
rotation direction of a cyclone in the southern hemisphere
Clockwise Direction
Cyclone Classification where winds is up to 61 kph
Tropical Depression
Cyclone Classification where winds is up to 62 - 88 kph
Tropical Storm
Cyclone Classification where winds is up to 89 - 117 kph
Severe Tropical Storm
Cyclone Classification where winds is up to 118 - 220 kph
Typhoon
Cyclone Classification where winds is exceeding up to 220 kph

Signal No. 3
Storm Warning System when winds are up to 171 - 220 kph in the next 24 hrs
Signal No. 4
Storm Warning System when winds are up to more than 220 kph in the next 24 hrs
Signal No. 5
storm that originates near central pacific ocean, north atlantic ocean and eastern pacific ocean
Hurricane
Storm that originates from the northwest pacific ocean
Typhoon
Storm the orignates from the south pacific and indian ocean
Tropical Cyclone
Hot and Moist wind from the Indian Ocean, brings rain over the western seaboard
Habagat or Southwest Monsoon
Dry and Cold wind from Siberia which weaken tropical cyclones
Amihan or Northeast Monsoon
