It is the size and complexity of current global climate models that make them mostly useless to understanding the atmosphere and climate. (climateaudit.org)
They are not resolved in current global climate models, a fact that colors all of climate modeling. (gfdl.noaa.gov)
Why it matters: Current global climate models used to predict climate change account for large - scale climate processes, typically at scales greater than 100 kilometers, or about 62 miles. (pnnl.gov)
