Sentences with phrase «global reanalysis models»
We will analyze synoptic - scale weather patterns from global reanalysis models over the past 50 years, utilizing a variety of techniques including self - organizing maps, such that these weather patterns can be tied to variations in core proxies, as well as relate this to ten years (2003 - 2013) of records from about a dozen automated weather stations located on and near McCall Glacier.

It is not difficult to calculate the actual potential intensity from SST and atmospheric soundings, and this can be done as well for reanalysis and global model data sets.
These climate - related land storage effects could be significant for global sea - levels, though unfortunately there seem to be very few direct experimental measurements of the factors involved, and so the only studies of these effects seem to have been from computer modelling of data from weather data «reanalysis» models (e.g., ERA - 40).
I'm interested to use a global reanalysis data to force hydrological models such as SWAT for a meso watershed with sparse hydrometeorological stations.
MERRA is a NASA reanalysis for the satellite era using a major new version (circa 2008) of the Goddard Earth Observing System Data Assimilation System Version 5 (GEOS - 5) produced by the NASA GSFC Global Modeling and Assimilation Office (GMAO).
Type 2 dynamic downscaling refers to regional weather (or climate) simulations in which the regional model's initial atmospheric conditions are forgotten (i.e., the predictions do not depend on the specific initial conditions), but results still depend on the lateral boundary conditions from a global numerical weather prediction where initial observed atmospheric conditions are not yet forgotten, or are from a global reanalysis.
Errors associated with using this statistical model to determine the global average time series is estimated by subsampling the observations (primarily ship tracks) in the earlier period against reanalysis data for the modern period.
Metzger et al. (NRL Stennis Space Center), 5.0 (3.4 - 6.0), Modeling The Global Ocean Forecast System (GOFS) 3.1 was run in forecast mode without data assimilation, initialized with July 1, 2015 ice / ocean analyses, for ten simulations using National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) atmospheric forcing fields from 2005 - 2014.
NRL - ocn - ice, 5.2 (4.3 - 6.0), Modeling (ice - ocean) The Global Ocean Forecast System (GOFS) 3.1 was run in forecast mode without data assimilation, initialized with June 1, 2016 ice / ocean analyses, for ten simulations using National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) atmospheric forcing fields from 2005 - 2014.
ECMWF's approach to reanalysis combines measurements of temperature and other meteorological variables with a global weather model to provide a complete picture of the regional patterns of climate.
A reanalysis system is a global large scale numerical forecast model (currently a numerical approximation of the ill posed hydrostatic system, e.g. the ECMWF model) that assimilates (inserts or mixes) observational data in with the numerical model forecast in an attempt to obtain a better set of global data.
The difference is that the reanalysis process involves using the observations to inform a physical model in order to construct a global average, whereas the other estimates use statistical models.
