Pressure and Wind
Constant pressure charts are useful for looking at upper atmospheric features, such as this steering current
What is the jet stream?
This is the main hazard associated with downslope winds, such as the Santa Anas
What is wildfire?
Jet streams are driven by differences in this key atmospheric characteristic
What is temperature?
This is the fastest moving of all the weather fronts
What is the cold front?
Long waves in the upper atmosphere are also known as this
What are Rossby waves?
This is the most commonly used constant height chart
What is the sea level, or surface, weather map?
These breezes occur during the day, and feature cooler air from the water flowing towards warmer rising air over land
What are sea breezes?
What is the Indian Ocean?
This front is symbolized by alternating purple triangles and semicircles on a weather map
What is an occluded front?
An area where the upper level flow bulges northward, characterized by relatively warm air and high atmospheric pressure, is called this
What is a ridge?
Wind naturally flows from areas of _____ pressure to areas of _____ pressure
What is from HIGH to LOW?
These breezes occur during the night, and feature winds that blow from high towards low elevations
What are mountain breezes?
This, the stronger jet stream, is found near 50-60 degrees of latitude
What is the Polar jet stream?
What is the dryline?
An area where the upper level flow dips southward, characterized by relatively cold air and low atmospheric pressure, is called this
What is a trough?
In the northern hemisphere, winds rotate in this direction around a low pressure system
What is counterclockwise or cyclonically?
These breezes occur during the night, and feature cooler, high pressure air from the land flowing towards the water
What is a land breeze?
This jet stream is found between the Ferrel and Hadley cells
What is the Subtropical jet stream?
This slow moving front is the feature a cold front catches up to and merges with when making an occluded front
What is a warm front?
When a short wave enters a trough, it can cause this to develop at the surface
What is a storm?
The Coriolis force deflects objects to the ____ in the northern hemisphere
What is the RIGHT?
These breezes occur during the day, and feature winds that blow from low towards high elevations
What are valley breezes?
In the thermohaline circulation, dense and cold water sinks in the northern regions of this oceanic basin
What is the Atlantic Ocean?
This type of thunderstorm, which can potentially create many tornadoes over their lifespan, often forms along a dryline
What is a supercell thunderstorm?
Upper level convergence leads to the formation of this surface weather feature
What is a high pressure system?
