Episode notes
Santa Ana Winds Origin
- Santa Ana winds are downslope winds originating in an elevated basin behind the Sierra Nevada.
- They accelerate down coastal slopes due to pressure gradients and gravity.
Unique Geography
- Downslope winds occur globally where mountains exist, but Santa Ana winds are unique.
- Southern California's geography, with the elevated Great Basin, makes these winds special.
Intensity of Winds
- Santa Ana winds are typically dry and warm, but this year's are exceptionally destructive.
- An unusual upper air support from the jet stream intensifies the wind flow.
