A Washington Post published two years ago contains information that has continuing relevance and should be kept under review by anyone interested in the threat posed by melting of Arctic permafrost.  The article was written in response to NOAA’s 2019 … Continue reading →

Why is it so cold? According to the weather maps, average air temperatures across the entire planetary surface are about the same today as they were around thirty years ago on the same day of the year. This is considered … Continue reading →

An important study was published one year ago that I should have reviewed in these letters but somehow overlooked at the time.  It dealt with a potential loss of a significant amount of the “carbon sink” that we depend on … Continue reading →

Yesterday’s letter described a potent heatwave now occurring in the very heart of the Arctic region. An event like this is most unusual in the month of January, especially considering the fact that two separate sources of extraordinary heating, in … Continue reading →

Two large atmospheric rivers (ARs), one originating in the Pacific and the other in the Atlantic, have extended their reach deep into the heart of the polar zone—so deep that now only a thin band of territory separates their leading … Continue reading →

Atmospheric rivers are composed of one kind of material, called precipitable water (PW). PW is entirely composed from one kind of molecule, H2O, a molecule commonly found in any of three different states of matter, liquid, vapor or solid. PW … Continue reading →

When you open Today’s Weather Maps https://climatereanalyzer.org/wx/DailySummary/#t2 and click on Precipitable Water the map you get is really two maps in one.  It also shows you the location of every atmospheric river in operation for that day.  If you scroll … Continue reading →

Recent studies add more clarity to the definition of atmospheric rivers (ARs). Today’s letter will mainly consist of links to these studies plus quotes. I have started to use the term AR quite aggressively, and want to make sure I … Continue reading →

“The greenhouse energy effect of atmospheric rivers” This is a subject I will be writing about for awhile, and not so much about the greenhouse effect of precipitable water (PW). This is a conceptual upgrade, one that I am excited … Continue reading →

I’ve found a new and better way to describe the greenhouse energy effects of precipitable water (PW). PW is a term that has little cognizance and stimulates little interest. You seldom hear it used by the media and scientists do … Continue reading →
