ICYMI Oct 24 – World Record Temp/Hole Punch Clouds/Seymour

The world record high temperature of 134 degrees was set in Death Valley (Furnace Creek), CA on July 10, 1912 …but did it?

There has been research as to the validity of the report. Back in February of 2013, there was a paper published showing, what was through to be the world record (136° in northern Libya), the reason why that record was no longer a valid record.

This would now make the 134° report at Death Valley the world record. Well…not so fast. Click here and take a look at some research that has been done on that temperature reading just posted. As of now 134° is the record. We will wait and hear from the World Meteorological Organization (WMO) says about it.

ICYMI Sept 19…Antisolar Rays & Belt of Venus /90° Days/Baseball Sized Hail

Severe storms were in the forecast for this afternoon and evening, but little to nothing materialized. The reason for that is because of what is called a CAP. This is small layer of the atmosphere that is warmer and it prevented the air from rising quickly.

___________________________________________
The high temperature today was 89 degrees in Cedar Rapids. I went back and looked to see how often does a high temperature of 90 degrees get reached in September at Cedar Rapids. Well, on this date is has done eight times. The chart below shows the calendar day at the bottom and temperature on the left. Each bar shows the number of days the temperature reached 90 or higher on that particular day. So again, on the 19th it was 90 or warmer 8 times on that day. Notice how fast the frequency drops off toward the end of the month…not very often.

There is a great web page very interesting photos and descriptions of why things look the way they do. Les Cowley puts off of this information on the web page. There is a section called Optics Picture of the Day. I learn something new every time I go the web page. The photo is just one example of some great photos on there. Here is the link.

Moon Dogs and Sun Dogs

In the last 24 hours we have had the chance to see a lot “dogs” in the sky. In the last few weeks Sun Dogs have been seen. Something that is not as common is a Moon Dog. The Moon Dogs are formed the same way as Sun Dogs are, but the light source is the moon not the sun. Jan 17 Moon Dogs Jan 17 Sun Dog

Light Pillars

When you were out this evening did you see the lights “shooting” up into the sky? Those are called light pillars. They form as light is reflected by horizontal ice crystals. Here is photo from Josie Petersen taken in Cedar Falls.
