UCP大会预览

概览:

此次会议主题为云与降水,从尺度上看,涵盖了微尺度到气候尺度;从方法上,则囊括了模式与观测。

会议分成了四个session,但是在开会的一周里,session都是相互穿插的,就连海报也是按姓名排序,可见主题之间的划分界限不会十分严格。

参会人有两百多,比想象中规模要大一些(因为似乎按照组织者原意,是想让所有人都有机会oral,并且更接近研讨会的味道),于是开了海报环节。而会议地点设在MPI的guest house里,据说空间不会太大,到时会有些拥挤。

会议的日程大体安排出来了,Oral的只有标题,poster的只公布了展示者姓名。所以,具体内容是什么样的还不是分明了。看了一下与会者,似乎大部分都是陌生面孔,在Paper里也读到不多,一方面是来的很大部分是欧洲的researcher、博士后与学生,教授和PI们做的领域跟我大概也有一些距离,我只认得其中的几名比较活跃的云物理大牛,不过这倒是好事,都知道了也就没有去与会的必要了,毕竟也是增进了解和交流的。

过两天研究一下各个session的发言人,看看有没有需要特别focus的部分。只希望到柏林能早点把时差调整好。

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.

LaTeX学习笔记

学得快也忘得快,今天捡起许久不用的LaTeX花了不少时间,为方便今后使用,把一些常用的东西写下,也顺便为路过的朋友们提供一些帮助。

LaTeX数学符号表达方式:

如何使用empheq数学工具包编辑方程:http://texdoc.net/texmf-dist/doc/latex/mh/empheq.pdf

complete latex symbol list doc: http://tug.ctan.org/info/symbols/comprehensive/symbols-a4.pdf

个例:

1 插入带编号方程

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\begin{document}
\begin{equation}
\equation
\end{equation}
\end{document}

2 插入联立方程组

\usepackage{empheq}
\begin{document}
\begin{empheq}[left=\empheqlbrace]{align}
\equation1\\
\equation2
\end{empheq}
\end{document}

3 标记方程

\begin{equation}\label{eqn:my equation}
\equation
\end{equation}
cite equation here \eqref{eqn:my equation}

如何在windows7上利用MikTeX安装软件包(package):

首先,创建一个软件包安装路径。新版的MikTeX不允许在软件子目录下创建路径,所以找个软件目录以外的地方创建,比如创建一个c:/localtexmf。根据读取软件包规则,文件路径必须至少包含以下嵌套关系:“tex/latex/软件包文件”,否则无法读取软件包。创建完后到开始->MikTeX->Maintanance(Admin)->Setting->Root下,添加总目录。比如以上例子,添加“c:/localtexmf”为其root.

其次,解压软件包。一般下载到的软件包中安装文件格式为.ins,有时也会是.dtx。用MikTeX打开任意一个,并用TeX命令或者XeTeX命令执行,结束后会生成一个.sty文件,把它复制到刚才创建的安装路径中,就可以使用了。

创建安装路径详细方法:http://tex.stackexchange.com/questions/69483/create-a-local-texmf-tree-in-miktex

安装方法:http://tex.stackexchange.com/questions/187725/how-to-install-mathtools-package

过程中如果出现“Not a TDS compliant root directory”是因为软件包安装路径名未按照要求的嵌套规则创建。

如何在LaTeX中插入图片

比如插入一副在文件夹figs中名为myfigure.jpg的图

\usepackage{graphicx}
\graphicspath{ {figs/} } %图片文件夹名
\begin{figure}[h]
\centering
\includegraphics[width=0.7\textwidth]{myfigure.jpg}\\
\caption{Sketch of detection cell}
\end{figure}

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.
