Probable Maximum Precipitation Studies
North American Weather Consultants has conducted detailed regional and site-specific
Probable Maximum Precipitation (PMP) for watersheds in the U.S. upper Midwest (Wisconsin,
Michigan and Ohio), the Southeast (North and South Carolina) and in the West (Colorado and
New Mexico). The studies have been requested by dam owners/operators who are facing
regulatory agency dam licensing or re-licensing requirements. They have chosen the
site-specific study approach as an option to utilizing the generalized PMP values found in
federal Hydrometeorological Reports (HMR's). To date, with only a few minor exceptions,
the studies have indicated lower PMP/PMF for the basins, and, following acceptance, have
resulted in significant savings to the owners/operators. In addition to savings in
construction and remediation costs, the lower PMP values have offered our clients enhanced
water management options. Acceptance of studies has been granted by the appropriate
regulatory agencies, the Federal Energy Regulatory Commission for dams with hydroelectric
power facilities, and the various State Engineers' Offices.
The studies are primarily storm-based, incorporating climatologies of historic extreme storms and regional precipitation. Building upon a foundation of accepted storm evaluation techniques, such as found in the HMR's, a number of important regional and site-specific basin characteristics which affect the occurrence and location of PMP-level storms and the production of extreme precipitation are also considered in detail. Some key factors include basin elevation, regional and basin terrain influences, available atmospheric moisture, seasonality of storm types, and storm maximization, positioning and orientation. This combination of techniques and evaluation factors results in refined, study area-specific PMP estimates. North American Weather Consultants will tailor a site-specific or regional study to your specific basin characteristics and needs. Drop us a note if you would like further information.

North American Weather Consultants maintains a library of long-term weather records for the U.S. and many other regions around the world. We can research historical meteorological records in a given area to provide a profile of meteorological conditions for that area. Means, extremes values, standard deviations of such parameters as precipitation, temperature and wind data can be calculated. Return periods for various parameters can be calculated. Examples of such calculations are 100-year maximum wind gust, 100-year maximum hourly precipitation, maximum expected snow-loading, or return frequency for an extreme weather event such as a tornado, hurricane or damaging wind storm. North American Weather Consultants uses the latest statistical techniques to derive long term return values using relatively short duration representative data sets.

North American Weather Consultants (NAWC) has signed an exclusive three-year licensing agreement with the University of Utah Technology Commercialization Office effective March 30, 2007. The agreement grants NAWC the exclusive right to use University of Utah patent # 5628455. An embodiment of the patented invention is a method for the reduction of supercooled fog, which comprises introducing liquid carbon dioxide into the fog from and along the ground by moving vehicles, in a quantity to diminish the supercooled fog. The method is of potential value in activities in which poor visibility due to the presence of supercooled fog is a constraining factor (e.g. winter airport operations). Please see Fog Dissipation for details.
Expert Testimony (Forensic Meteorology)
North American Weather Consultants has extensive experience in providing expert testimony at hearings and in conjunction with litigation. North American Weather Consultants professionals are able to translate complex technical issues and empirical data into information that is useful to the courts or decision-making agencies. We specialize in providing testimony with regard to atmospheric dispersion conditions (odor and/or health issues), reconstruction of meteorological conditions related to accidents, or general testimony on a wide variety of meteorological issues where the input of an atmospheric expert can be important in deciding a case. Please contact us for more information.
Specialized Meteorological Forecasting
North American Weather Consultants operates a complete synoptic forecast laboratory with access to all the latest meteorological measurements (surface and upper-air) from around the world. Many activities are subject to weather conditions. Outdoor sporting events or construction activities, for example, can be negatively impacted by adverse weather conditions. Specialized weather forecasts can be effectively utilized to minimize such negative impacts. Our meteorologists can provide specialized forecasts for a wide variety of situations such as:
|Site-specific precipitation/temperature/wind forecasts|
|Atmospheric dispersion/weather forecasts needed for outdoor activities|
|Construction site forecasts|
|Quantitative precipitation forecasts|
|Maximum/minimum temperature forecasts|
|Ship/truck routing forecasts|
If your specific needs are not listed here or we can be of further assistance, please contact us by emailor phone (801) 942-9005.
Meteorological Data Archival and Retrieval
Are you in need of some historical weather data? Do you need to archive data from a certain location for later use (such as dispersion modeling)? Do you need to prepare some meteorological data for dispersion modeling input? North American Weather Consultants has upper air (rawinsonde) data from all U.S. sites from the 1940s to the present. We have in-house information on most historical meteorological data collected in the United States and considerable data available for sites abroad. If there is a station for which you need surface or upper air data archived, we may be able to assist you with this as well. If you require meteorological data which we do not have, we can most likely find it. Please contact uswith any requests.
Radar-Derived Rainfall Estimates
Hydrologists and engineers frequently face difficulties when attempting to estimate rainfall for storm reconstructions or a variety of design applications. All too often, rain gages in a region of interest are not particularly representative of a specific point or area of interest.
Time-resolved estimates of rainfall using weather radar records can be derived for points or areas where adequately representative gage measurements are not available. The coverage of National Weather Service NEXRAD (next generation radar) sites provides rich data over most portions of the U.S. Careful processing and analysis of data from the NEXRAD radars can provide rainfall estimates at time intervals as short as 5-6 minutes.
We have the data sources, software and expertise to assist you with your rainfall estimation needs and can produce time-resolved spreadsheet data ready to use with your analysis package. Using tested data extraction techniques and objective navigation methods for precipitation trajectories, combined with calibration using rain gage data to determine the proper reflectivity-rainfall (Z-R) relationship, we can provide the data you need in a timely manner. We have successfully supported other clients and stand ready to assist you.
