how does a warm front move and what weather can you expect
Slow moving acts as warm blanket
Stratiform clouds
Poor visibility bc air is stable and calm
Steady precipitation
what is an isobar
equal line of pressure
what kind of visibility will you have
good vis
what kind of visibility will you have
what is a stationary front
where 2 fronts meet head on and sit there for a long period of time
widely spaced isobars
weaker pressure gradient lower wind speeds
why is a low pressure system unstable
rising air
How does high pressure affect density altitude
High pressure means lower density altitude
what is Frontogenesis
Beginning of a front
how do isobars show air pressure
Lines of equal pressure between highs and lows
what is another name for low pressure system
cyclone or depression
what is another name for high pressure system
what is Frontolysis
end of front
When looking at a surface analysis chart, what do tightly packed isobars around a low-pressure center indicate?
steep pressure gradient and thus strong, gusty winds and potential turbulence.
