A few days ago there was a post regarding Harvey Leonard talking about climate change on air. In tonight’s WHDH weather blog post, Pete Bouchard links the crappy weather pattern we have experienced lately with climate change.
There are many reasons for stalled weather patterns, but I believe the biggest is the lack of sea ice from climate change. An open ocean leaves a lot of heat in the poles. This fosters high pressure (or blocks in the jetstream), and with very little movement to weather patterns at the top and bottom of the globe, we get pinned down in these long periods of heavy precipitation/drought and hot or cold.
The image in his post is worth a minute or two of study. Do click on the link and read the explanation.
Kudos to Bouchard. I don’t know if he mentioned this on-air, but at least it is in the blog. Hopefully, we are seeing the start of a trend where the meteorologists on TV, radio, and the net start tying the larger weather picture with the change in climate.
