Climate Letter #1881

The close numerical association between total precipitable water (PW) and surface air temperature, as I wrote about yesterday, is now very much on my mind and occupying most of my attention. I think it has the makings of an important … Continue reading

Climate Letter #1880

Today I’ll be opening three current maps that help to illustrate some of the things I have been writing about the past few days. One of he most basic understandings relates to the simple fact that low values of total … Continue reading

Climate Letter #1879

Regular readers know that I have developed my own theory about a major source of global temperature changes. The theory is focused primarily on short-term changes, the kind that show up on the daily anomaly charts, but does not exclude … Continue reading

Climate Letter #1878

Yesterday I wrote about three separate ways that greenhouse energy effects are produced in Earth’s atmosphere, how they are related, and how precipitable water (PW) inhabiting the upper levels of the troposphere, historically a relative latecomer, has assumed a leadership … Continue reading

Climate Letter #1877

For quite some time I have been composing these letters around various arguments associated with the basic idea that precipitable water (PW) is the preeminent producer of greenhouse energy effects. One argument is that, outside of the tropical belt, the … Continue reading

Climate Letter #1876

The connection between global warming and severe outbreaks of cold winter weather has suddenly become a hot topic for media outlets everywhere, deservedly so because the relationship is not just unclear, but counterintuitive.  Reporters are giving us a chance to … Continue reading

Climate Letter #1875

Because of the disastrous conditions occurring in Texas, for which no proper preparations had been made, studies related to the polar vortex are sure to proliferate in coming months.  There is an acute need for more and better answers. The … Continue reading

Climate Letter #1874

What exactly is the polar vortex?  An excellent description by a pair of US research scientists has been presented in an article written for The Conversation, available at this link:  https://theconversation.com/what-exactly-is-the-polar-vortex-153958. I think the authors are on exactly the right … Continue reading

Climate Letter #1873

A big change today. We’re going back to the same spot in the corner of west Texas that had the anomaly of at least -28C yesterday, with a precipitable water (PW) reading between 5 and 6kg. Today the PW reading … Continue reading

Climate Letter #1872

The North American cold wave has produced a (for me) first-time event on the anomaly map that is surely worthy of a full description. On the map you will see a couple of small, lightly shaded spots in west Texas … Continue reading
