DISCUSSION: In lieu of the impactful nor’easter that produced rain, snow, wind, coastal flooding, the whole atmospheric sink essentially, let’s take a look at this storm system now and in the near future on a global perspective. Attached below is an animated global surface wind map, (courtesy to weatherTap for providing these mesmerizing world-view products). What is incredible about this product is how expansive it shows the wind field of our nor’easter. This nor’easter easily has the largest wind field of any storm on the planet at this time with winds 30 – 50 knots from east and north of Nova Scotia stretching down across much of the western Atlantic and to around 25 degrees North. Of course, we see tropical storm Dumazile churning just east of Madagascar as well in this imagery. Watch as Dumazile intensifies as the loop progresses through tonight and into the afternoon on Sunday March 4th (see the loop below as well).
Shifting to another feature of this world view is the predictive radar. This is exactly what it sounds like, a radar that animates into the future on a global scale. There are a bunch of features that can be examined with this radar. The big Alaskan Low is shown beautifully, with a nice comma head look in the precipitation, (also evident in the surface wind animation above!) Our nor’easter is shown as a large band of precipitation originating just off the North Carolina coast arching just off the New England coast and south of Nova Scotia and stretching back south and east across the central Atlantic. Another amazing simulation of the incredible size of this system.
Farther east, the active pattern in Europe continues with rounds of precipitation accompanied with some wind impacting much of western Europe in both animations.
Another interesting feature shown is the strong cyclone across far southeastern Russia with a trailing cold front potentially producing heavy rain and snow across much of Japan over the next 24 hours. Watch both loops and check out the similarities to the cold fronts experienced on the U.S East coast!
This is just a minor look at the features weatherTap Global has to offer and how it can be used to study the global weather. Be sure to stay tuned to more global winter analysis here!
