Realtime Analysis and Forecasting with ARPS

Operational Analysis and Forecasting with ARPS

CAPS has served the meteorological community since 1997 by continuously providing real-time numerical analyses and forecasts. CAPS realtime high-resolution weather analyses and forecasts throughout the year can be accessed through the CAPS/wx system.

Realtime Analysis with ADAS at University of Oklahoma

ARPS Data Analysis System (ADAS) is being run daily to produce hourly analysis for the southern great plain. This is an effort by Keith Brewster in parallel to the CAPS real time analysis and forecast operation.

University of Utah Realtime ADAS Analysis

Realtime analysis is being done with ADAS at the Department of Meteorology, University of Utah. It is part of the Utah Mesonet Project.

Oregeon State University ARPS Real time forecast

Once each day, ARPS is run for a region encompassing Western Oregon and much of the Pacific Northwest. This modeling effort is the result of cooperation from several departments at Oregon State University including the College of Oceanic and Atmospheric Sciences (COAS) and the Department of Mechanical Engineering.

ARPS is being used to produce regional forecasts at Galicia region of northwest Spain.

Hongkong Observoatory is also doing experiment forecast using ARPS in Hongkong area.

Testing of ARPS in Korean Environment (TAKE)

ARPS is being tested at Korean Meteorological Agency (KMA) since 1997, mostly during the Changma (Meiyu) seasons (July - August). A conference paper summarizes the efforts in 1997.

Operationalization of ARPS model for commonwealth games 2010 at India Meteorological Department

ARPS will be run initially during 07-12 UTC every day at NWP center, India Meteorological Department, New Delhi, India for commonwealth games 2010 to be held in DELHI during 03-13 Oct. 2010. Products will be avaialbe at http://www.imd.gov.in/section/nhac/dynamic/arps.htm.

Past Real Time Forecast Projects at CAPS

Hub-CAPS Project

Project Hub-CAPS (see Carpenter, et al., 1999), a 3-year research and development partnership between American Airlines and the University of Oklahoma to adapt storm-scale numerical weather prediction technology for commercial airline operations. This project has now been merged with the regular CAPS real time forecast effort.

SAMEX'1998

A multi-institutional NWP experiment during spring, 1998 convective season over the central US. Known as SAMEX '98 (Storm and Mesoscale Ensemble Experiment, spring 1998), this effort involves a realtime comparison of approximately 30 ensemble forecasts, run at 30 km resolution using 3 models, against forecasts run at both intermediate (10 km) and high (2-3 km) resolution over sub-sets of the ensemble domain.

CAPS SAMEX'98 Forecast Experiment

ARPS was run at part of SAMEX'98 during May 1998, at 27/9 km resolutions, on PSC's massively parallel Cray T3E, using 128 processors. The forecast products are at http://origin.caps.ou.edu/~samex/arps/.

CAPS storm-scale forecasting experiment during VORTEX'95

The ARPS model is being run daily through June 1995 in support of the VORTEX project. Participants in this evaluation include the NOAA NSSL, the Norman NWSFO, the NOAA SPC, and the OU School of Meteorology. Forecasting results are summarized in Droegemeier et al (1996a) and Xue et al (1996a).

CAPS spring operational period during 1996 (SOP96)

The 1996 CAPS Spring Operational Storm-Scale Prediction Experiment is a collaborative effort among OU's CAPS, the Norman NWSFO , the NOAA SPC, and the National Aviation Weather Center (AWC). The principal goal is to conduct high-resolution, short-term numerical predictions of convective weather on a daily basis, and to evaluate the quality of these forecasts in operational settings. Forecasting results are summarized in Droegemeier et al (1996b) and Xue et al (1996b).

COMET-Tinker Project

The goal of the COMET-Tinker Project is to evaluate the forecasting effectiveness of the ARPS mesoscale model by Air Force weather personnel. This project is a cooperative effort between the School of Meteorology (SOM), at the University of Oklahoma, and the 72nd Air Base Wing Weather Flight at Tinker Air Force Base, Oklahoma. The project is funded by the COoperative Program for Operational Meteorology, Education and Training (COMET) Outreach Program of the University Corporation for Atmospheric Research (UCAR) and by the Air Weather Service (AWS) of the United States Air Force.
