The Climate Consensus @climateconsensus.bsky.social · 19/09/2026The airflow between the low and high pressure systems increases the AR’s wind speed and constrains the flow of warm, humid air into a narrow region between the 2 systems. 100
The Climate Consensus @climateconsensus.bsky.social · 19/09/2026A steeper pressure gradient leads to stronger winds as a result of geostrophic balance, which is an approximate balance between the pressure gradient and Coriolis force. 100
The Climate Consensus @climateconsensus.bsky.social · 19/09/2026During the winter season, ARs occur over both the western and eastern U.S. Over the modern satellite era (1980-2020), a decline in AR activity over the Western U.S. leads to a drying trend, while increases over the Eastern U.S. lead to a moistening trend, largely resulting from strong events. 100
