I am pleased to announce that the Senior Learning Institute (SLI) of the College of Central Florida in Ocala is providing me another opportunity to present a geosciences topic that is near and dear to me.
IMPORTANT SPECIAL UPDATE (5-10-2015): The Senior Learning Institute no longer exists. It has become the non-profit Senior Learners, Inc. and classes are still taught at the College of Central Florida in Ocala. Here is a link:
IDENTIFYING AND UNDERSTANDING CLOUDS will be presented on Feb. 5, 7, 12, 14 (2013) – from 10 until noon (for a total of 8 hours). Click on the following link for my outline which will be distributed at the beginning of the first class meeting.
I have presented a dozen seminars at the SLI since 2006 and thoroughly enjoyed them. Since I taught a 12 hour course on clouds in April, 2007 I have received requests from a number of people who missed it and also from others who wished to do it again as a refresher.
SLI is a membership group composed of some terrific people who seem to consider “learning” to be an integral aspect of their life styles. When I am with them, though my official roll is that of a presenter, I learn so very much. I learn from them and I learn in the processes of preparing and presenting. There are some significant differences between these courses and the courses I taught for 41 years at colleges and universities: 1) the SLI seminars are non-credit courses, 2) they are short in duration compared to most college courses, 3) there are no academic prerequisites to the courses, 4) there are no exams to fret over, 5) there are no grades, 6) all who enroll are there voluntarily and, from what I can tell, gladly and 7) many have a great deal of experience acquired through time and by their sharing are able to enhance the quality of the course.
The photo below is actually from a scan of the “full disk” of earth from the GOES-13 satellite. I have cropped the original in order to concentrate upon Tropical Storm Irene. Tropical Storm Jose also shows up in the image; it is very small. To find it look for a small blob of clouds, bright white (about half the width of the state of Florida and located off the Carolinas and next to Bermuda). More information follows after the image.
TWO INDEPENDENT LEFT CLICKS WILL ENLARGE TO THE FULLEST.
TIME OF PHOTO – 2:45 pm Eastern Daylight Time
DATE – Sunday, August 28, 2011
ALTITUDE OF SATELLITE – about 22,300 miles
TIME NEEDED TO SCAN FULL DISK OF EARTH – about 26 minute

I was out pulling weeds around 8 pm EDT at my home in Citrus County, Florida when I saw cirrus clouds moving along at a fairly good clip. After taking a few quick photographs, I went to my computer to confirm what I suspected I was seeing. I consulted both an up-to-date satellite visible loop and an infrared loop. Sure enough, the cirrus I was observing marked the outermost segment of an outflow band from hurricane Irene.
Here is a photo as I faced the WSW. (The gray clouds are little fracto-cumulus at a much lower altitude than the very high cirrus).
The graphic below shows the general direction of movement of both the inflow and the outflow of a hurricane in the northern hemisphere. This particular one is hurricane Ike of 2008.
