The final weekend of the Olympic games likely won’t be as wet as the first weekend. (It was wet I know!) But it will still be wet. For the next week we have a pretty respectable 110mm of rain in the forecast.
Doesn’t look like any major events will hit us. Just some days or evenings of good steady rain.
I did also want to mention a report that was released a few days ago. For the past few years, a common refrain from some corners of the climate community has been that there could be more or stronger hurricanes in a warmed world. Scientists acknowledged a possibility, but there was no hard evidence, or at least any hard research to back that up.
Well, now there is, and the verdict is a bit of both.
The research is published here, in Nature Geoscience, and it says:
it remains uncertain whether past changes in tropical cyclone activity have exceeded the variability expected from natural causes. However, future projections based on theory and high-resolution dynamical models consistently indicate that greenhouse warming will cause the globally averaged intensity of tropical cyclones to shift towards stronger storms, with intensity increases of 2–11% by 2100. Existing modelling studies also consistently project decreases in the globally averaged frequency of tropical cyclones, by 6–34%. Balanced against this, higher resolution modelling studies typically project substantial increases in the frequency of the most intense cyclones, and increases of the order of 20% in the precipitation rate within 100 km of the storm centre.
Now of course we don’t get tropical storms here directly. But we do certainly have periods, especially in the October/November/December timeframe when former tropical storms “curl” back towards us from Japan and the West Pacific and give a little extra punch to our storms.
2% isnt much in terms of wind … but a 20% increase in precipitation certainly would not be very welcome down on 3rd ave.
