Record heat and Dan

#1 Postby Mike Doran » Mon Jul 24, 2006 2:14 am

The good news was this weekend at a Chico California swim meet my 6 year old daughter got a trophy for high points -- the bad news was our family had to spend the weekend outdoors in record heat.

As many of you know I look at cloud microphysics and electrics. I look at Dan as a giant capaciter--and the Pacific high as impacted by the same kinds of forcings on larger scale viscosities. As Dan lost it's annular organization--as a consequence looking at him as a giant capaciter the 'C' goes to zero and voltages rise in the ionosphere for shorts to ground and then there is the available discharging current and as a consequence the Pacific high went CRAZY high.

The SOI index also rose, which is a measure of pressure between Tahiti and Darwin. To me the SOI is also interesting because as cloud cover and pressures change along the Pacific ITCZ, so does CONDUCTIVITY and couplings.

Saturday in Redding California--90 minutes from Chico, where we live:

112 deg F Sat record for July 22 110 deg f

Today was 114 deg F officially. The record temp for today WAS 109 deg F, but for month of July all time record is 118 deg F on July 20 1988--that's the year of Gilbert when the Mississippi was at a low flow rate just prior to its occurrance. There are only 6 other warmer days than today in Redding recorded history and that includes one day in August that was over 114 degF. See

A heat advisory was issued and pressures were EXTREMELY high.

It was just terrible to be outside in that heat but my daughter got to jump in a pool. Parents did not have that luxury.

Oh come on, it's just a little physics! You know, E&M? :lol:

I'm still hoping that Mike can put together a post sometime that lays out the basics of this electric side of meteorology; sounds like it might be interesting.

And that's why I enquired what the letters DAN stand for. :) I knew by reading his post that this particular Dan isn't obviously in reference to a person. :wink:
