First Snowfall of the Season

First snowfall of the season in Stormstown, PA. The forecast today called for a chance of snow showers (60%). Instead, there was moderate snow, starting around 10 AM EST. Later, the flakes started to fall in clumps.

Air temperatures remained well above freezing for most of the day, so there was little or no accumulation in the area. However, to the southwest, in The Laurel Highlands, travel was affected significantly.

Harvey and Irma Are Not A Sign of Climate Change

at201711_sat Sorry climate alarmists, but you can not blame this year’s major hurricanes on climate change, global warming or whatever you want to call it.

Posting on the Watts Up With That blog.

Prior to this season, there haven’t been any major hurricane landfalls in The United States since Wilma in 2005. This season is simply an anomaly. In fact, the frequency of major hurricanes has been decreasing.

NYT Says We’re Too Dumb To Understand Climate Change

By Robert Tracinski I recently wrote about the wretched reporting on the claim that 2016 was the “hottest year on record,” using as my main example a New York Times article by Justin Gillis that gave his readers none of the relevant numbers they could use to evaluate that claim. None of them. If you…

Yes, where are the error bars?!

First Day of Pyranometer Operation

In a previous post, I talked about installing a new pyranometer to my weather station. Below is a graph of today’s solar radiation flux in W/m^2.

The graph clearly shows when the instrument was in shade (7:30 – 9:30 AM EST). Maximum value was after noon due to the fact that the longitude is about 3 deg west of the 75th meridian and because the equation of time for today is 3 minutes. The maximum solar elevation angle was about 28 deg. The optical depth of the atmosphere is significantly higher at such a low angle than if the sun was at zenith.
