Society was formed in 1967 from a branch of the Royal A Word about the Meteorological Society. In 1977 when the oceanographic community joined, the name of the Society Society was changed to the Canadian Meteorological and Oceanographic Society (CMOS). The Society was subsequently incorporated with this name in 1984. CMOS is a national society of individuals, centres and chapters dedicated to advancing all aspects of atmospheric sciences, oceanography, and related disciplines in Canada. The Society also offers accreditation of meteorological consultants and endorsement of media weathercasters. Fourteen Society centres and chapters across Canada serve as focal points for local and regional activities. Scientific interests of the Society include: operational meteorology, climatology, hydrology, air pollution, agriculture/forestry meteorology, mesoscale meteorology, floating ice, physical,

  • Snow Modeling and Observations at NOAA's National Operational
    Snow Modeling and Observations at NOAA’S National Operational Hydrologic Remote Sensing Center Thomas R. Carroll National Operational Hydrologic Remote Sensing Center, National Weather Service, National Oceanic and Atmospheric Administration Chanhassen, Minnesota, USA Abstract The National Oceanic and Atmospheric Administration’s (NOAA) National Operational Hydrologic Remote Sensing Center (NOHRSC) routinely ingests all of the electronically available, real-time, ground-based, snow data; airborne snow water equivalent data; satellite areal extent of snow cover information; and numerical weather prediction (NWP) model forcings for the coterminous United States. The NWP model forcings are physically downscaled from their native 13 kilometer2 (km) spatial resolution to a 1 km2 resolution for the coterminous United States. The downscaled NWP forcings drive the NOHRSC Snow Model (NSM) that includes an energy-and-mass-balance snow accumulation and ablation model run at a 1 km2 spatial resolution and at a 1 hour temporal resolution for the country. The ground-based, airborne, and satellite snow observations are assimilated into the model state variables simulated by the NSM using a Newtonian nudging technique. The principle advantages of the assimilation technique are: (1) approximate balance is maintained in the NSM, (2) physical processes are easily accommodated in the model, and (3) asynoptic data are incorporated at the appropriate times. The NSM is reinitialized with the assimilated snow observations to generate a variety of snow products that combine to form NOAA’s NOHRSC National Snow Analyses (NSA). The NOHRSC NSA incorporate all of the information necessary and available to produce a “best estimate” of real-time snow cover conditions at 1 km2 spatial resolution and 1 hour temporal resolution for the country.

  • A North American Hourly Assimilation and Model Forecast Cycle: the Rapid Refresh
    APRIL 2016 B E N J A M I N E T A L . 1669 A North American Hourly Assimilation and Model Forecast Cycle: The Rapid Refresh STANLEY G. BENJAMIN,STEPHEN S. WEYGANDT,JOHN M.

MANIKIN NOAA/NWS/NCEP/Environmental Modeling Center, College Park, Maryland (Manuscript received 8 July 2015, in final form 8 December 2015) ABSTRACT The Rapid Refresh (RAP), an hourly updated assimilation and model forecast system, replaced the Rapid Update Cycle (RUC) as an operational regional analysis and forecast system among the suite of models at the NOAA/National Centers for Environmental Prediction (NCEP) in 2012. The need for an effective hourly updated assimilation and modeling system for the United States for situational awareness and related decision- making has continued to increase for various applications including aviation (and transportation in general), severe weather, and energy. The RAP is distinct from the previous RUC in three primary aspects: a larger geographical domain (covering North America), use of the community-based Advanced Research version of the Weather Research and Forecasting (WRF) Model (ARW) replacing the RUC forecast model, and use of the Gridpoint Statistical Interpolation analysis system (GSI) instead of the RUC three-dimensional variational data assimilation (3DVar). As part of the RAP development, modifications have been made to the community ARW model (especially in model physics) and GSI assimilation systems, some based on previous model and assimilation design innovations developed initially with the RUC.

  • Executive Summary Workshop on Improving ALE Ocean Modeling NOAA Center for Weather and Climate Prediction College Park, MD October 3-4, 2016
    Executive Summary Workshop on Improving ALE Ocean Modeling NOAA Center for Weather and Climate Prediction College Park, MD October 3-4, 2016 A one-and-a-half-day workshop on ocean models that employ the ALE (Arbitrary Lagrangian-Eulerian) method to permit general vertical coordinates was held at NCWCP on October 3-4, 2016. Four different ALE models (GO2, HYCOM, MOM6, and MPAS-Ocean) were discussed. Workshop participants included users and developers of these models, from academia and from seven different national modeling centers (ESRL, GFDL, GISS, LANL, NCAR, NCEP, NRL). A more detailed report on the workshop follows this executive summary, and a workshop agenda with a list of workshop speakers is attached as an appendix. A number of recommendations for future action were developed during the meeting. The recommendations fall into four broad categories: Code Sharing, Community Building, Code Merger and Performance and Future Development. The recommendations are listed below. 1. Code Sharing Sharing of common codes for the equation of state, grid generation and remapping, and column physics such as mixing parameterizations, is recommended. The group suggested making vertical remapping/grid generator routines an open source package that can be shared in the manner of CVMix. a. The development of prognostic equations for the grid generator based upon physical mixing should be considered. b. We recommend open-source GIT repositories (hosted on code-sharing sites such as Github) for submodules such as CVMix. c. We recommend the development of common tests for self-consistency, conservation, and known solutions. 2. Community Building d. The ALE modeling group should consider whether semi-regular meetings similar to this workshop should be undertaken; perhaps via merger/inclusion with the Layered Ocean Model workshop.

  • Guidelines for the Preparation of Final Papers for EUMETSAT Conferences
    Proceedings for the 13th International Winds Workshop 27 June - 1 July 2016, Monterey, California, USA STATUS OF THE OPERATIONAL SATELLITE WINDS PRODUCTION AT CPTEC/INPE AND IT USAGE IN REGIONAL DATA ASSIMILATION OVER SOUTH AMERICA Renato G. Negri, Luiz F. Sapucci, Lucas Avanço, Nelson Ferreira, Luiz G. G. Gonçalves National Institute for Space Research, Center for Weather Forecasting and Climate Research, Rod. Pres. Dutra, km 40, Cachoeira Paulista, SP, 12.630-000, Brazil Abstract Tropospheric winds are estimated using satellite imagery since late 60's and today they are a very important source of information for numerical weather forecasts. The CPTEC/INPE has being producing Atmospheric Motion Vectors (AMV), operationally, since early 2000's, using GOES satellites. The typical spatial coverage is the South America and surrounding oceans covered by the GOES satellites. The wind extraction at CPTEC/INPE is done using the visible, near infrared (3.9 µm) water vapor absorption (6.7 µm) and window infrared (10.2 µm) channels. The visible and 3.9 µm are used only to estimate the low level winds for day and night only respectively, 6.7 µm allows to estimate winds at middle and high troposphere and 10.2 µm is used to estimate the wind at all tropospheric layers. This algorithm makes use of triplets of successive GOES images with at least 30 minutes between each pair, which allow having a new wind field at least half hour. The quality control applied to the wind fields is based on developed at EUMETSAT where each AMV receive a quality indicator and the final users can choose what level is more suitable to their application.
