There is an 80% chance that a disturbance in the Gulf of Mexico will become a tropical cyclone, a named storm, over the next couple of days. If that happens it will be called Bill. Possible Bill is not well defined and is poorly organized. The disturbance is currently near the Yucatan, and will move…

Joe and Mary built a house. They built it on an old flood plain of a small river, though there’d not been a flood in years. This was a 500-year flood plain. Not a very floody flood plain at all. The local zoning code required that for a new house at their location the bottom…

Blanca is the second named tropical storm in the Eastern Pacific. I’m pretty sure Blanca was originally a disturbance with a low probability of becoming a named storm, but I may have missed something. Blanca is intensifying rapidly and will reach hurricane status shortly if it has not already, and will likely develop to become…

Ana is coming up the Atlantic

I remember joking with my friend Ana about how her name would be attached to the first named storm in the 2015 Atlantic Hurricane season. It turns out Ana is an exceptional individual. Both of them. Ana, my friend, is an actor and is currently engaged in a project I’ll be telling you more about…

A paper just out now in PNAS by Noah Diffenbaugh, Daniel Swain, and Danielle Touma shows that “Anthropogenic warming has increased drought risk in California.” From the abstract: … We find that although there has not been a substantial change in the probability of either negative or moderately negative precipitation anomalies in recent decades, the…

Pam is a tropical cyclone of category 5 strength, but is churning over waters that have high temperatures at depth, a phenomenon we seem to be seeing more often lately, as a result of anthropogenic global warming. That is why I call it “AGW Class.” Strong Category 5, deep heat enhanced. It is said that…

Human caused greenhouse gas pollution has warmed the planet. Global warming means more extreme weather. Many meteorologist who watch the weather every day see this. More and more research shows that greenhouse gas pollution changes the weather in a way that causes even more change in the weather. Changing weather systems means more lightning, increased…

A newly published study has identified changes in precipitation patterns in the US Northeast, which are likely caused by human pollution of the atmosphere with greenhouse gasses, which has resulted in global warming. According to the study, there has been an increase in extreme precipitation events, and an increase in the clumping across time of…

Boston Snow Climate Change Amplified

New England is now experiencing the fifth in a series of worse than average winter storms. So far, Winter has dumped over 60 inches of snow on Boston, and after the present storm, it will probably be possible to say that a total of 60 inches or more have fallen there in just over 2…

What happened to the Blizzard of 2015?

What happened to the Blizzard of 2015? Well, it happened. Despite breathless complaining about how the forecasters got it all wrong, they didn’t. As the storm was predicted, there should have been close to about two feet of snow in the New York City metropolitan area, but as it turns out, there was between 8…
