Weather discussions by Gert & Dave during the 2020 Atlantic Hurricane Season. The homepage with the links to local reports from the islands, latest satellite image, current weather outlook can be found here.
That brings me to my second topic, a paper was just published in PNAS by NOAA scientist, noting that climate change ("global warming") is indeed causing stronger storms, esp. in the Atlantic. See also this article in the Washington Post. This is a big deal since storm force increases exponentially (not linearly) with windspeed. The little sidebar on the right shows that there is a big difference in storm force between the different category hurricanes, even though windspeeds differ only by about 15-25 mph. In the WP news article, meteorologist Elsner is quoted as: "Hurricane destruction in the United States, in terms of physical damage costs, has historically increased by 10 percent for every 5 mph increase in wind speed".
The PNAS study finds that the chances of a storm becoming Category 3 or higher is increasing about 8 percent per decade. Also, not only are storms stronger, and due to higher seawater temperature, wetter, they also seem to intensify much more quickly, like Amphan did, and as we have recently seen in the Caribbean, like Maria. So, unfortunately it looks like we will see more 'big ones' in the future... More the reason to be well prepared... -Gert
This is the 6th year in a row that a tropical storm has formed before the official start of hurricane season (June 1) according to Brian McNoldy. He also shows that there is indeed a trend that storms form earlier. However, no need (yet?) to change the official start of hurricane season, because it is still pretty seldom that a hurricane forms outside hurricane season (see the First Storm of the Season page, hmmm, I really have to update that with more recent data). -Gert

- It's that time again!
The new names are posted above. The names repeat every six years. Remarkable storm names are retired, but since 2014 was a quiet season, none were taken of the list. Although some names, like Arthur, Berth, Dolly and Edouard sound eerily familiar from previous seasons... -Gert
The no shadow effect should make for some interesting pictures. See for example the Pringles can below with no shadow made by Hogan. Jurgen posted some on the Barbados page as well. Since we are all spending a lot of time at home now, maybe a fun thing to do is make a creative picture and post it (or send to me if you are not a correspondent)! Make sure that your object or whatever is on a level surface.
If your island is not listed you can follow Hogan's directions below to find the exact date/time for you:
Use the Heavens Above website: Select your Location
Click on 'Sun' and look at Maximum Altitude, then change the date until you see the figure in the altitude column get as close to 90 as possible.
This is also a good website if you want to see the International Space Station go over; on the main page click on Satellites - ISS. Lots of other useful info too.
Enjoy, looking forward to see some creative photos! -Gert
