The Impact of a Low Bias in Snow Water Equivalent Initialization on CFS Seasonal Forecasts
Publisher: American Meteorological Society
Abstract: AbstractAcross much of the Northern Hemisphere, Climate Forecast System forecasts made earlier in the winter (e.g., on 1 January) are found to have more snow water equivalent (SWE) in April?June than forecasts made later ...
Why Do Global Reanalyses and Land Data Assimilation Products Underestimate Snow Water Equivalent?
Publisher: American Meteorological Society
Abstract: here is a large uncertainty of snow water equivalent (SWE) in reanalyses and the Global Land Data Assimilation System (GLDAS), but the primary reason for this uncertainty remains unclear. Here several reanalysis products ...
A New Snow Density Parameterization for Land Data Initialization
Publisher: American Meteorological Society
Abstract: now initialization is crucial for weather and seasonal prediction, but the National Centers for Environmental Prediction (NCEP) operational models have been found to produce too little snow water equivalent, partly because ...
An Evaluation of Snow Initializations in NCEP Global and Regional Forecasting Models
Publisher: American Meteorological Society
Abstract: now plays a major role in land?atmosphere interactions, but strong spatial heterogeneity in snow depth (SD) and snow water equivalent (SWE) makes it challenging to evaluate gridded snow quantities using in situ measurements. ...
