What the weather maps are saying about global temperatures at this time. We may be in the middle of a record breaking year for warmth but it does not look at all like that right now. This next image offers … Continue reading →

There are many stories in the news about a major heatwave settling in across southwestern parts of the US, where temperatures are soaring to new records in some places. Much less is being said about a much larger and stronger … Continue reading →

Thoughts about temperature anomalies.  I have been studying Today’s Weather Maps virtually every day for the past several years and have become more and more fascinated by the kinds of information they provide.  As you may have noticed in yesterday’s … Continue reading →

There is a nice piece of map study waiting for us today. I am going to turn it into a challenge that will make it kind of fun for anyone who has gotten familiar with how these relationships work and … Continue reading →

An intensified study of high-altitude water vapor should provide new information that would deepen our understanding of how the planetary weather system works, and climate too.  Could this be of any help in a practical sense, for purposes of mitigation?  … Continue reading →

Today, a bit of map study about the critical role played by high-altitude streams of precipitable water in establishing surface air temperatures.  We are going to zero in on a specific portion of North America and use temperature anomaly readings … Continue reading →

Arctic sea ice is disappearing at a record pace this summer.  Please open this interactive website for a clear picture that is easy to follow with day-by-day comparisons to other years:  https://ads.nipr.ac.jp/vishop/#/extent/&time=2019-04-01%2000:00:00   Until a week ago this year’s melting progress … Continue reading →

The anomaly described in yesterday’s letter does not appear to have strengthened today. The whole thing has actually shifted toward the east by maybe fifty or a hundred miles, and so has the large but weaker cool anomaly that can … Continue reading →

An interesting warm anomaly of considerable size has emerged in eastern Asia, depicted below.  It may have the potential to develop into a major heatwave so we will need to keep a close eye on it. The anomaly stretches from … Continue reading →

Friday’s letter provided evidence that current temperature changes in Antarctica at this time of year are almost totally dependent on changes in the precipitable water content of the air directly above the surface.  The data displays also show the enormous … Continue reading →
