Today I will discuss the “big picture” of what is going on with our planet’s climate, using full global images for illustration.  (These should be preserved anyway for later comparison because of the great amount of disorder currently affecting the … Continue reading →

There are several points of interest I want to focus on today, mainly related to things that cause differences in daily temperatures in the Arctic region.  We’ll start by opening the air temperature anomaly map, where you can immediately see … Continue reading →

Yesterday we saw the image of a 500hPa air pressure configuration in the Arctic that was badly distorted for this time of year, and what the consequences were like. The major jetstream pathways defined by the outer borders of the … Continue reading →

Another good day for map study, showing a number of different interconnections in unmistakable detail. It will start with the pattern that was set for high-altitude air pressure differences at and above 500hPa. The degree of disorganization for this time … Continue reading →

Are you ready for another demonstration of the power of precipitable water (PW) to alter surface air temperatures?  Today we are getting a whole plateful of extreme-anomaly examples to work with on one single mapsite.  I will shorten things up … Continue reading →

I’ve been alerted to a website that has a full year (2019) of animation for global precipitable water (PW) in one brief video, which is kind of fun to watch: https://www.youtube.com/watch. Seasonal changes are there to be seen, if you … Continue reading →

Yesterday’s letter produced one example of vivid graphic evidence in support of my basic claim re the relationship between precipitable water (PW) and surface air temperatures.  What I presented was a limited amount of raw data from purely visual sources, … Continue reading →

There is a fascinating conjunction of extreme temperature anomalies in the Weather Maps today that has a story to tell, nicely illustrated. Over and over again I have made the claim that, when everything else is equal, including the day … Continue reading →

The argument I have been making contends that surface air temperatures around the globe are highly dependent on the amount of precipitable water (PW) in the atmosphere directly above any particular location.  It further contends that large changes in surface … Continue reading →

Why the study of precipitable water is a matter of critical importance. The short answer is because it may have a significant bearing on the way climate forecasting is done.  We all have a deep interest in that subject, and … Continue reading →
