Climatology Definitions Flashcards
Weather
Condition of atmosphere in particular place
Meteorologist
Study weather
Climatologist
Study climate
Climate
Average weather conditions in area for long period (20-30 years)
ITCZ
Zone that changes according to season
Heat balance
Balance between the energy that the Earth receives from the Sun and that which is radiated by Earth
Radiant energy
Energy transmitted invisibly in the form of waves
Insolation
Incoming solar radiation
Solar constant
The amount of solar radiation that reaches the Tropopause.
Terrestrial radiation
Heat energy that is radiated by the earth
Convection
Transfer of heat by vertical movement
Latent heat
Transfer of energy when condensation occurs
Conduction
Transfer of heat by contact
Absorption
Taking up of light or heat
Reflection
The bouncing back of light or heat
Scattering
Sent in all directions
Diurnal
Daily
Annual temperature range
Difference between the summer and winter temperatures in a year
Maritime climates
Moderate temperatures due to the influence of the oceans
Continental climates
A climate with extreme temperatures which occurs in places far from the sea
Air saturation
Water is holding the maximum amount of water vapour it can at existing temperature
Water vapour capacity
Maximum amount of water vapour that air can hold at certain temperature
Saturated air
Air has reached this capacity
Lapse rate of temperature
Variation of temperature with height
Environmental lapse rate
Change of temperature with height in atmosphere
Positive lapse rate of temperature
Temperature decreases with height
Negative lapse rate of temperature/Inversion
Temperature increases with height
