It’s July 25th, So Why Is It So Cool in the South and Midwest?

Summary


Introduction

The weather data is speaking to us, when will we listen?

In this article, I explain how to use the global warming daily digest that I created a couple of weeks ago. Here is the link to that article.

Be sure to watch the video included in this article to gain a much better appreciation of why global warming isn’t always what we think it is!


For My Alteryx Inspire Presentation Attendees

This article was written for the people that attended my Alteryx Inspire presentation in May in Nashville, TN. The audience heard me make these predictions, including my guess as to why these changes are happening.

As time goes by, the perturbations in the jet stream seem to be the culprit that is causing the cooling zones I have identified throughout space and time, as shown in Figure 1.

Here is the July 25th Daily Digest Graphic

Some people might think I’m showing Figure 2 to say that I told you so, but I’m not doing that. I just want to show the relationship between the jet stream and the cooling zones that develop. There are >950 stations highlighted in this picture that show an average of -2.7 degrees (cooling) since 1960.

Figure 2 – The total temperature change from over 950 stations on July 25th. Look at the relationship between the blue circles that are highlighted and the jet stream shown in Figure 1.


How the July 25 Daily Digest Explains the Mid-Summer Cooling

The cool temperatures being experienced today are NOT UNEXPECTED! The weathermen think this type of cooling is just random chance. It is NOT! It is predictable using the past 6 decades of data from July 25th.

Listen to the story in the video below.

The Coarse Temperature Change Distribution For this Cooling Period

The mid-west temperature changes predicted from 12 midwestern and southern states is shown in Figure 3. For those areas, the average change is -98% of the global warming average. This means that rather than showing 1.7 degrees of heating since 1960, these 537 stations show an average of -1.7 degrees, which is significant cooling.

This change is less than what is shown in Figure 2 because I was less precise in defining the cooling zone. In Figure 3, the histogram is based on state boundaries rather than selecting the entire cooling zone of 950 stations, as I did in Figure 2. By selecting state boundaries, a number of stations that have exhibited heating are also included, thereby reducing the average cooling from -2.7 to -1.7 deg F.
