The Climate Letter archive from last year holds an image of high-altitude air pressure configuration on April 15 that I will show here so it can be compared side by side with the one for today. They are both in … Continue reading →

Here is something you don’t see very often, as both poles are being warmed up by close to +10C at the same time: Meanwhile, the numbers under the map tell us the planet as a whole is undergoing a cool … Continue reading →

There are new developments affecting the seasonal warming trend in the Arctic region that will be reported in today’s letter. The images you see can be compared with those in Monday’s letter, which are easily accessible on this website. The … Continue reading →

If a relatively small amount of precipitable water (PW) traverses over the Arctic Ocean at this time of year, what damage can it do? That’s my subject for today. By using the Weather Maps we can come up with some … Continue reading →

A new Arctic warming season with special summertime features is now getting underway. I expect it to be at least comparable to the one we experienced last summer and will follow the proceedings closely as it develops. The archive of … Continue reading →

Some of the things I have been writing about lately are coming into full bloom, creating images on the weather maps that serve well as illustrations. We certainly want to know what will happen if and when the blue zone … Continue reading →

Thanks to the incredibly helpful visual imagery provided by Today’s Weather Maps, we are able to identify the locations of three major pathways of jetstream wind activity in each polar hemisphere. We can also examine the actual wind behavior on … Continue reading →

We have looked at the current configuration of high-altitude air preesure in detail at each of the two polar zones, with a focus on the blue-shaded zones in each hemisphere.  We noted how the borders of each of the two … Continue reading →

Yesterday’s letter offered some details of a possible relationship between high-latitude surface air temperatures in the Northern Hemisphere and the positioning of an important pathway bearing jetstream winds at an altitude which could only begin at not less than about … Continue reading →

Today’s Weather Maps, https://climatereanalyzer.org/wx/DailySummary/#t2 published daily by the U of Maine, are a tremendous source of weather and climate information.  Twelve different basic maps are featured (plus two with variations) covering a wide assortment of phenomena.  If you sort through … Continue reading →
