Clouds

I never wrote any articles about clouds in my blog until today I happened to read Dr. Ian Strangeways’s book of Precipitation: Theory, Measurement and Distribution and its chapter of Cloud formation.

I’ve read dozens of books on clouds & precipitation, but “it takes the last straw to break a camel’s back”. This book is the last straw I finally make up my mind to write something.

Cloud microphysics is a new born child compare to the long-existing meteorology. It was not until new technologies booming in the last century that made high-resolution measurements inside real clouds and computer model simulations possible.

Although the first scientific cloud classification started from the era of Luke Howard (1802). The more sophisticated and complete classification was introduced by WMO in 1975 & 1987 in its International Cloud Atlas. As I was reading Strangeways’s book, I got to know that weather (a journal by RMS) spent a whole issue in 2003 to address the bicentenary of Luke Howard’s classification. The issue is free to public if you are interested http://onlinelibrary.wiley.com/doi/10.1002/wea.v58:2/issuetoc .

I wish I could say something more profound so that I could be regarded wiser. But whenever I looked at clouds, whenever I was reading any good academic/non-academic publications on clouds, I felt humble and always found myself innocent.

The world is so big. Clouds can be found anywhere in the sky. The weather and climate are uncertain, largely because of the present of clouds.

Endnote issue of “This URL could not be launched” [solved]

I could not re-open the attached pdf file in endnote. Every entry I tried gave me the same error stating “This URL could not be launched”. At first I believe it has something to do with the URL itself. However, when I right click the attachment and click “save as”, the file can be successfully migrated to another directory. Then the URL has no problem at all since the software can locate the file.

I googled it and found same issue has been reported and solved in endnote forum. The official explanation is that the problem come with the conflict between different Adobe PDF viewing programs. Then I just realized that I have both Adobe reader and Adobe Acrobat in my system. That’s why they fighting with each other and confusing my system?

They offer a solution that is to run a window batch file to choose one default program. Well that was too much for me. And I got another quick and neat solution from China’s Sciencenet forum: Right click any pdf file and select the “Open with” item. Click “Choose default program” and then choose the program of your choice and check”Always use the selected program to open this kind of file”.

I chose Adobe Acrobat and problem solved.
