An extreme weather pattern for parts of the U.S. is expected to continue to stick around for the next several days. There is a large upper level trough of low pressure stalled across the central U.S., and two areas of high pressure – one in the U.S. West and another across Bermuda – have been holding in place for the past several days. With no movement, this large trough has been unable to push out of the country, and this blocking pattern has brought tropical moisture streaming into the U.S. Southeast and major heat across the U.S. Southwest.
Can we link climate change with the current unusual weather pattern? According to a report released on October 2012 by the National Oceanic and Atmospheric Administration (NOAA), the warming of the Arctic and the overall planet can influence the orientation of the jet stream. According to the report: The effects of Arctic amplification will increase as more summer ice retreats over coming decades. Enhanced warming of the Arctic affects the jet stream by slowing its west-to-east winds and by promoting larger north-south meanders in the flow. Predicting those meanders and where the weather associated with them will be located in any given year, however, remains a challenge. The current weather occurring across North America is an example of what climate change can do to our jet stream over time.
