Today I will run a sequence of images like those of yesterday, but from a different region and with the focus changing to a much smaller scale. We’ll be looking at connections tied to the polyp shape of the 500hPa … Continue reading →

It’s an interesting day for map study because of all the bending and sprouting on the 500hPa air pressure map. The imagery on this map, as you may know by now, is basically established as a physical response to the … Continue reading →

I have often claimed that mainstream climate science shows no sign of interest in the greenhouse effect of precipitable water (PW), comparable to the way I describe it in these letters.  I should be ready to back up that claim … Continue reading →

After using this letter for about a full year to make comments about what the weather maps are telling us, I have come to realize that there is a certain amount of need for more individuals to become engaged in … Continue reading →

The work I have been doing is all based on the finding and interpreting of visual relationships that appear amongst the images that constitute the daily Weather Maps. The maps cover an extended variety of phenomena, some of which we … Continue reading →

A new way of defining “the blue zone.” Yesterday, when writing about the healthiness of the blue zone, as depicted on the upper-level air pressure map, my mind started to entertain a new idea. I could see that the zone … Continue reading →

Today, more observations keyed to the formation of the blue zone, which forms the heart of any image of the upper-level air pressure configuration. A “healthy” blue zone is one that assures the presence of plenty of cold air and … Continue reading →

The high-altitude configuration of air pressure differentials.  Does it have a critical role to play in the progress of long-term climate change?  This is a question I have had in the back of my mind for quite some time, at … Continue reading →

A theme I keep coming back to, rather cautiously, concerns the role of high-altitude air pressure configuration as a factor that affects the progress of climate change. It is a difficult thing to get my head around, and perhaps you … Continue reading →

In yesterday’s letter I offered a speculation about what the high-altitude air pressure map would have looked like during the time of the Eocene when the polar regions had tropical climates.  No blue zone, no green zone, just a lot … Continue reading →
