MM5 Model Development and User Support

The number of MM5 users who subscribe to our news list continue to increase this year. At the end of September, 2004, that number is 1120 from 566 institutions worldwide. About 2440 emails were answered in the year. A new user information and registration page (http://www.mmm.ucar.edu/mm5/institutes.html) has been developed by Cindy Bruyere and Kristin Conrad. The page has improved viewing and maintenance of the database. User pages on Frequently Asked Questions and computer related issues have been expanded to accommodate many users' need to run the modeling system on various new systems and/or with new compilers (such as the new Intel compiler).

WRF Model Development and User Support

The number of WRF users continued to increase in the last year. Another 800 people (in addition to the previous 1400) have visited the WRF site and downloaded the code. Over 960 users have subscribed to the WRF news list, compared to the 600 people reported last year. In May 2004, the WRF ARW, SI, and 3DVAR Version 2.0 was released in which the nesting capability was included. Two minor version releases were followed in late May and early June. The WRF User page has been redesigned and made its debut with the WRF Version 2 release in May. The number of user emails continues to increase. During FY04, W. Wang and other MMM staff answered 1130 user emails, which is a 66% increase over the previous year.

Model Workshops

- MM5 and WRF Workshop:
The Fourteenth Annual MM5 Users' Workshop was held on 22-25 June 2004 in conjunction with the Fifth WRF Users Workshop. About 170 participants arrived from 90 institutions worldwide. Twenty foreign countries participated. One hundred papers were received for the workshop. W. Wang, J. Klemp, J. Dudhia, and J. Powers organized the event.

Educational Activities for Models

- MM5 Tutorial:
We continued to offer a MM5 modeling system tutorial this year, in January 2004. The last one will be offered in FY05, January. A total of 35 participants (8 from foreign countries) from 28 institutions worldwide attended the classes. Jimy Dudhia, Dave Gill, Kevin Manning, Cindy Bruyere, Dale Barker, and Wei Wang lectured at the tutorials.

- WRF tutorial:
A four-day WRF followed the Users’ Workshop during the summer of 2004. The dates were 28 June – 1 July. The WRF model, WRF Standard Initialization, and WRF 3DVAR were taught at the tutorial. Practice sessions were a part of the WRF tutorial for the first time. In order to accommodate the 115 participants, sessions were divided. 75 institutions and 15 countries were represented. A new User’s Guide was developed and distributed at the tutorial. Cindy Bruyere, Shu-hau Chen (University of California, Davis), Jimy Dudhia, David Gill, Yong-Run Guo, Wei Huang,, John Michalakes, and Wei Wang, along with John Smart and Paula McCaslin (NOAA/FSL), lectured at the WRF tutorial.

Data Access and Analysis Software Support (top)

Sherrie Fredrick and Jay Miller continued support of the CEDRIC (Custom Editing and Display of Reduced Information in Cartesian space) software system that is used for the analysis of regularly gridded datasets from
both numerical models and observational systems. This software package continues to be used heavily by researchers at universities and government agencies, both domestic and foreign.

Fredrick modified CEDRIC source code to output MDV format from CEDRIC.

Field Campaigns (top)

AIRS-2: (Second Alliance Icing Research Study II) aims to investigate the microstructure and spatial distribution of mixed phase clouds. Aaron Bansemer participated in the late Fall 2003 study in Colorado.

AWEX: (AIRS Water Vapor Experiment) is a part of the AIRS program (Second Alliance Icing Research Study II). Larry Miloshevich was the PI for this study.

CIFEX: (Cloud Indirect Effects Experiment). Carl Schmitt was an investigator in this study. This experiment was held during April 2004.

CME-04: (Carbon in the Mountains Experiment) This experiment was set up in the mountains west of Boulder, Colorado, at Niwot Ridge. in the Spring and Summer of 2004. Jielun Sun, Edward Patton, Donald Lenschow, Sean Burns participated.

ACME: (Airborne Carbon in the Mountains Experiment) is the first aircraft field campaign of a program supported by the NSF Biocomplexity Program and NASA Interdisciplinary Science. The goal of the project is to understand carbon dynamics in mountain forest regions by developing new methods for estimating carbon exchange at local to regional scales.

M-PACE: (Mixed-Phase Arctic Clouds Experiment) The major objective of the project is to collect the focused set of observations needed to advance the understanding of dynamical processes in Arctic mixed-phase clouds, including the cloud microphysical processes and radiative transfer through the clouds. Aaron Bansemer participated in this experiment during late September early October 2004.

MidCIX: (Mid Continental Cirrus Experiment) Andrew Heymsfield was the principal investigator and Aaron Bansemer participated on the instrumentation. Project was in California.
NAME: (North American Monsoon Experiment) was conducted in July and August 2004 in La Cruz, Sinaloa, Mexico. James Done and David Ahijevych participated . The objective was an improved understanding necessary to advance warm season precipitation prediction. It is an internationally coordinated, joint CLIVAR-GEWEX process study aimed at determining the sources and limits of predictability of warm season precipitation over North America, with emphasis on time scales ranging from seasonal-to-interannual.

OHATS: (Ocean Horizontal Array Turbulence Study), is a collaborative effort between NCAR, Woods Hole Oceanographic Institute, and Pennsylvania State University. The field experiment was held south of Martha’s Vineyard to investigate wind-wave interactions and improve our ability to assess the impacts on weather forecasts and climate variability. Time-frame was August to October 2004.

Principle Investigators from MMM for the project are Peter P. Sullivan, Donald Lenschow, Chin-Hoh Moeng, and Jeffery C. Weil (long-term visitor from CIRES, University of Colorado). Edward Patton (long-term visitor from Pennsylvania State University) and Jielun Sun participated.

Pentagon Shield Field Program: Part of the DARPA project, long-term visitor from CIRES, University of Colorado, Jeffrey Weil was the co-director of this program which was held from 4/29/04 to 5/10/04. The purpose was to model fine-scale flow around the Pentagon, and to determine the impact of point/continuous chemical release on the building.

Pre-AVE: (Pre Aura Validation Experiment) occurred in January 2004 in Costa Rica, sponsored by NASA. Andrew Heymsfield and Alan Hills participated.

RAMS-2: (Riming, Aggregation, & Melting Layer Study) was scheduled during March 2004. Aaron Bansemer was one of the investigators.

Looking Ahead……..

RICO: (Rain in Cumulus over the Ocean) will study the use of S-Pol, C-130, Dropsondes, and SABL to measure precipitation processes and to determine their importance in shallow, maritime, cumulus convection, one of the prevalent cloud types on the planet. This project will be held in November 15, 2004 - January 24, 2005 in Antigua, Barbuda.

RIME: The Ross Island Meteorology Experiment, a basic and applied research program, will explore in detail the atmospheric processes over Antarctica and their interactions with lower latitudes via the Ross sea sector, as a prerequisite to exploring the role of Antarctica in global climate variations. Local and regional measurements to be made during the summer-early fall of 2005/2006 and the spring of 2007 will be complemented by an extensive numerical modeling effort to accurately simulate and understand transports of heat, water vapor, and mass to and from Antarctica along with their modification by the topographic and mesoscale processes. Jordan Powers is involved in the planning stages and strong international collaborations will be a hallmark of RIME that will span June 2003 to June 2010.

Collaborative Visits to Universities and Agencies

John Latham had two month-long collaborative visits to the University of Manchester Institute of Science & Technology in the UK, one in June and July of 2004 and another in September of that same year.

Richard Rotunno visited the University of Trento, Italy from August to November 2003
and University of L’Aquila, Italy from November to December 2003.

Piotr Smolarkiewicz finished his five-month collaborative visit at Yale University in December 2004.

Visitor Program

Collaboration and study has led to much of the success in research within MMM. The MMM Visitor Program speaks strongly of this. Senior scientists, professors, students, all have gathered here as members of the meteorological community. MMM hosted 463 visitors during FY04. Forty percent of these visitors arrived from foreign countries.

The Affiliate Scientist program within NCAR enabled MMM to work closely with six outside scientists (during FY04) for the duration of three years or longer. Based on an agreement between their university and NCAR, these scientists and their MMM hosts desire an extended, highly interactive set of opportunities. The six Affiliate Scientist appointments during FY04 were: Lance Bosart (State University of New York, Albany), L. Ruby Leung (Pacific Northwest National Laboratory) (shared with CGD), and Douglas Lilly (University of Oklahoma), Larry Mahrt (Oregon State University), Bjorn Stevens (University of California, Los Angeles), and Xiaolei Zou (Florida State University).
