Contours are rainfall totals from the Canadian Precipitation Analysis, which combines
weather model output with station measurements to estimate regional precipitation amounts.
I have used
weather model output extensively for forecasting weather and air quality and it is amazing how well our modern weather models can forecast the weather for several days compared to what I saw in college days in the early 1970's.
Not exact matches
The scientists examined four different versions of the
model outputs, each one translated for the region with data from
weather stations in the Northwest through a process called «downscaling.»
Thanks to its amazing
output and all - wheel - drive system, this new
model promises to deliver «outstanding handling and all -
weather performance capabilities.»
Now scientists have concluded this century, that this natural variation «
weather» signal can be large enough to put a significant mismatch between
model output and current decadal temperature record.
Model outputs do produce specific year - to - year fluctuations — fluctuations that are not hindcasted well (that's the
weather, after all)-- but nobody's interested in knowing the exact temperature of any particular year.
Output, generated on the monthly time scale, is disaggregated to daily values with a
weather generator and used to drive soybean yields in the crop
model DSSAT - CSM, for which preliminary results are discussed.
They are not alone as all parts of climate science lack data, use estimated data, rely on computer
model output based on no data, and ignore natural causes of
weather and climate change.
Working from collision data from Transport Canada,
weather data from Environment Canada and the
output of regional climate
models, they explored how future changes in precipitation could effect road safety in the Greater Vancouver area.
Operational
Weather Forecasting covers the whole process of forecast production, from understanding the nature of the forecasting problem, gathering the observational data with which to initialise and verify forecasts, designing and building a
model (or
models) to advance those initial conditions forwards in time and then interpreting the
model output and putting it into a form which is relevant to customers of
weather forecasts.
The impact of low shortwave fluxes came out well in two - week forecasts of a semi-empirical break - up
model forced with
output from a long - range
weather forecast (contribution by Petrich and Eicken).
Climate change was assessed by means of two Long Ashton Research Station -
Weather Generator (LARS - WG)
weather generators and all
outputs from the available general circulation
models in the
Model for the Assessment of Greenhouse - gas Induced Climate Change - SCENario GENerator (MAGICC - SCENGEN) software, in combination with different emission scenarios at the regional scale, while the Providing Regional Climates for Impacts Studies (PRECIS) model has been used for projections at the local s

Finally, there's consensus that we can not look at climate forecasts — in particular, probabilistic forecasts — the same way we view
weather predictions, and none of us would sell climate -
model output, either at face value or after statistical analysis, as a reliable representation of the complete range of possible futures.
