IPCC GFDL Precip Anomaly (3 mb)Intergovernmental Panel on Climate Change - Precipitation Anomaly from 1870-2199
Description:
"The Intergovernmental Panel on Climate Change (IPCC) was established by WMO and UNEP to assess scientific, technical and socio- economic information relevant for the understanding of climate change, its potential impacts and options for adaptation and mitigation. It is open to all members of the UN and of WMO." - from www.ipcc.ch In an effort to better visualize the future of climate change, the IPCC releases assessment reports on the current state of the atmosphere and what the future could hold. Models from various atmospheric and oceanic organizations are included in these reports in order to establish a broad understanding of the science. Data from three of the IPCC models following temperature change from 1870 - 2199 have been formatted for Science On a Sphere®.
The model for precipitation anomaly that is available was developed by the Geophysical Fluid Dynamics Laboratory. The model uses the same forcing agents as the temperature change model and the sea ice model, but is set to determine precipitation anomalies. For the past data, the 20th Century Model 20C3M is used, which takes into account the historical record of greenhouse gases, sulfate aerosol concentrations, volcanic aerosol optical depth, and historical solar irradiation. For the future, the SRES A1B is used; a scenario which assumes very rapid economic growth with low population growth and the introduction of new and more efficient technology. In this model, CO2 production increases until it reaches 717ppm near the year 2100; then it is cut off.
The precipitation anomaly is the difference from what is normal. In this case, normal was defined as the precipitation averages for the year 2000. Red shading is used to signify areas that will receive more rain than in 2000, and the blue shading represents areas that will receive less rain than in 2000. Unlike the temperature models which show a warming trend over almost the entire globe, the precipitation anomaly is varied across the globe with time showing no clear trend.
