Thought I would post this here to see if anyone had any ideas about it.
I have been watching different weather sites and taking snapshots of temperature maps for a couple of weeks. I ran into a site call coolwx. The temperature analysis snapshots are here. The bottom of the page has 24 frames for hourly snapshots and there is a current animation of the past 24 hours here.
In saving some of the animations I noticed some anomalies in some of them. The anomaly is basically an oval heat island that appears and disappears in the northern parts of North American, north Canadian provinces usually.
I couldn't get the gif animations I saved uploaded to where they can be viewed so I took frame snapshots to post here.
Here are the first snapshots, from around Dec 26 2008, five frames:
Oval shaped anomaly in NW Territories / Yukon
Oval shaped anomaly in NW Territories / Yukon
No Anomaly
Oval shaped anomaly in NW Territories / Yukon
No Anomaly
Here is a three frame sequence from Jan 06, 2009:
No Anomaly
Oval shaped anomaly in Mid Southern Saskatchewan
No Anomaly
And three frames more recently (about 24 hrs ago):
No Anomaly
Oval shaped anomaly in Central Saskatchewan
No Anomaly
The images aren't displaying full sized here on the forum, but basically the heat islands I find rather strange. My first inclination is to think they are anomalies in the data itself or the humans creating the images. I am not sure of the source of the data, if it is from a NOAA sat or some other satellite data stream or something else. If it is a data anomaly from detector errors in a satellite then there is a big problem somewhere. It could be artifacts in the data stream??? But that seems kind of weak also.
The anomalies are oval with smooth perimeters. Each shows heat from a small central area, cooling outward to the perimeter of the oval. If these are valid they are very strange. They occur in areas where it is less than -10 degrees F (at the times these areas were as much as -30). Their central cores are +40 degrees F to +60 degrees F. So these huge holes pop up with a temperature differential swinging 50 to 70 to even 80 degrees Fahrenheit and then go away and the area returns to its previous temp before the anomaly.
It all seems too farfetched to be anything other than an anomaly, but I am reminded of the scrubbing of the hurricane Rita infrared anomalies that were caught by 'University of Wisconsin-Madison - Cooperative Institute for Meteorological Satellite Studies -Morphed Integrated Microwave Imagery'. CIMSS left the original data up for Rita and then in three weeks scrubbed it and changed the images.
I think this session was asking about the CIMSS images on Rita.

(J) I want to know about these strange formations on the radar image of Hurricane Rita.

I am wondering if these heat islands (if not just data errors) are more practice, maybe trying to modify the arctic front to alter its blow to the States?
