Definitions for topic 1: Climate and Weather Flashcards
weather
short-term/daily atmospheric conditions
climate
long term average weather conditions observed over +- 30 years.
meteorology
the scientific study of weather and climate
mid-latitude cyclones
LP systems associated with meeting warm and cold air masses.
Polar front
Boundary/transition zone between 2 diff air masses (warm + cold) at 60 degree latitude
warm front
where warm air rises above heavier cold air
cold front
where cold air wedges in under lighter warm air, causing it to rise.
occluded front
where cold front overtakes warm front and warm air is isolated from surface.
cyclogenesis
development (or strengthening) of cyclone circulation
dissipate
lose energy/fade away
tropical cyclone
intense LP system associated with extreme weather conditions.
latent heat
energy released when water vapour condenses (into water droplets)
vortex
rotating, whirling movement of air
eye wall
the band of cloud surrounding the eye of a tropical cyclone
storm surge
offshore rise of water (to abnormal levels) caused by strong winds of LP system (causes coastal flooding)
