#2 Flashcards
Stationary Front
Cold Front meets warm front causing them to start fighting against each other, caused by neither being powerful enough to overpower the other, wind moved parallel to the fronts strengthening stationary front
Surface Analysis Chart Shows
Pressure Systems, Isobars, fronts, air masses, and station info
Isobar defined
Isobar is defined as equal pressure area
Close Isobars Defined
The closer the isobars the larger pressure difference could be warning signs of convective or strong surface winds
Cloud Types
Stratus - Thin (Stable Air)
Cumulus - Puffy (Unstable Air)
Nimbus - Rain Cloud (unstable lifting force and high moisture)
Fog - Ground Cloud (Dewpoint/Temp equal or close to equal at surface)
Fog defined
Fog is a cloud that begins 50ft from the surface occurs when dewpoint/temp near surface are extremely close. Happens with temp reaches dewpoint or dewpoint reaches temp
Fog Types
Radiation Fog, Advection Fog, Upslope Fog, Steam fog, frontal fog, and Ice fog
Steam fog cause
Forms when cold air moves over warm water, cool air mixes with warm moist air the moist air cools and the humidity reaches 100%
Frontal Fog Causes
Warm raindrops evaporate to cooler drier air layer near the surface as it evaporates the humidity reaches 100% and fog forms
Radiation Fog causes
Happens usually on calm clear nights, during the day UV rays heat up the surface at night the UV rays are released from the ground and the surface cools to dewpoint
