Secondly, the spread around the model - mean value is calculated after the anomalies are taken which has the visual effect of minimizing the range of modeled temperatures. (patricktbrown.org)
All these complications have traditionally rendered attempts at modeling rainfall — which is much harder than modeling temperature changes — futile. (scientificamerican.com)
In the far south, the near - surface modeled temperature tend is in the opposite direction from the observations. (wattsupwiththat.com)
