this morning's balloon launch was successful, and there were no
issues. Looking at the sounding, the vertical profile is generally
dry throughout the atmospheric column. There is a small
temperature inversion at the surface, which will dissipate
throughout the day as the Sun causes atmospheric mixing to occur.
The CIN is higher today than usual for this time of year (-259
j kg in the mixed layer), and the CAPE is average for this time
of year (1677 j kg in the mixed layer). This combination could
lead to some small development of a few showers, but for the most
part, the higher CIN and average CAPE will inhibit thunderstorm
formation. The vertical wind profile is variable with height. At|
the surface and in the lower levels of the atmosphere, the winds
are westerly. At the middle levels and in the upper levels
(including at the jet stream), the winds are northerly and weaker
(around 30 knots). Msw

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
