Make Text Bigger on iMac or MacBook–Command +

In most applications on a Mac (email, text editors, web pages, etc.), just hold down the “command” key (on either side of the spacebar) and tap the “+” key. If it’s too big, hold down the “command” key and tap the “-” minus key.

If it’s text you typed, sometimes you need to select all the text (command “a” or click & drag) first.

Hope this helps!

Change Finder Windows View Style from the Command LIne in Mac OSX

Good article here.  Also can just open Finder and hit command+J and then hit the set as defaults button at the bottom of the pop up window.  

CFL Condition Bust

Problem today with the nested and single domain busting the CFL condition.  First started at 38 points, then went to 982, then 3622 points exceed cfl condition.  Then WRF blew up.  Need to adjust.  Wondering about convection occurring today causing the crash.

Decrease the time step to avoid the problem.

What is the difference between blue and green messages on the iPhone in iOS 5.0.1?

Great article explaining why you don’t need texting service if all your contacts are on iPhones because iMessage will take care of the texting for you.

green = SMS
blue=iMessage

If a conversation starts out on one method it will stay that way throughout the conversation.

PREDICT Follow on at AGU Fall Meeting 3-7 Dec 2012

http://fallmeeting.agu.org/2012/

Abstract Deadline: 8th Aug.

Session Details:

A060: Recent Field Experiments for Better Understanding and Prediction of Tropical Cyclones

Conveners:

1. Zhuo Wang, University of Illinois
2. Timothy J Dunkerton, Northwest Research Associates, Inc.
3. Patrick Harr, Naval Postgraduate School
4. Edward J Zipser, University of Utah

Description:

“Several major field experiments on tropical cyclones (TC) have been carried out in the past several years, including T-PARC, TCS08, GRIP, PREDICT, IFEX, and ITOP. A field experiment sponsored by NASA (HS3) will start in summer 2012. These field experiments focus on different stages of the TC life cycle. Data collected are expected to advance our understanding of TC formation, intensity change, and extratropical transition as well as to improve TC forecasts. Contributions are solicited for all observational analysis and modeling studies that make use of observations collected during these field campaigns to advance our understanding or to improve the forecasts of tropical cyclones.”

Total Precip Calculation from WRF

RAINC includes all phases of convective precip, and RAINNC includes all phases of non-convective precip. So total precip is given by RAINC + RAINNC.

Also note that WRF precip accumulates during the run and is never reset to zero, unless you specify this in the namelist.
Can any one please tell me how can I calculate the total precipitation  
from ARW-WRF output. Do I only need to add “RAINC + RAINNC” variables  
or I should also include “SNOWC + GRAUPELNC” with the former?

I would like to compare with meteorological station measurement, where  
they have calculated total precipitation as a sum of “Rain + Snow”.

How Shear is Calculated in the Tropics

Shear has been calculated for a long time using the vector difference between 200hPa and 850hPa total winds. It could be that zonal shear gives a reasonable approximation to total shear in the deep tropics where low-level easterlies meet upper-level westerlies in general. When all the data is available, however, it is definitely preferable to calculate and use total shear.
