Global Climate Models - Essay Example

Global Climate ModelsECHAM5/MPI-OM ModelThe ECHAM5/MPI-OM , 2005 is a coupled climate model that consists of atmospheric general circulation (AGCM) ECHAM5, and MPI0-OM ocean sea ice component that was developed at the Max Planck Institute for Meteorology (MPIM) in the year 2005. It is the fifth generation of the ECHAM circulation model. There are other models that were used before the ECHAM5/MPI-OM, 2005 model was designed. The coupled model can be used to compare the climate change in the ocean ecosystem as well as the atmospheric ecosystem (Bader, 2008).

Therefore, the model being coupled, it can be used to predict the global climate change. Furthermore, recent studies have shown that the model is very efficient in estimating global climate change. It has been adopted by many nations globally because of its effective understanding of climate sensitivity. Moreover, the ECHAM5 reproduces the global metrics of the tropical cyclones. The other submodels before the ECHAM5 include the ECHAM4 which reproduces the extremes and variability of rainfall (Randall and Wood).

BCC-CM1 Model.The model was developed in 2005 by the Beijin Climate Centre. It was designed as a global ocean, atmospheric global model to reflect or study the mean climatological state (Bader, 2008). Therefore, it was not designed climate change in China, but to be used all over the globe. Additionally, it is very important to note that this model is used to predict global and East Asian seasonal climate. It presents a very high resolution of climate forecasts in China and more so it produces monthly scale forecasts of the climate in this region (Palmer, 2014).

As a result, the monthly extended dynamic range system is thus based on the BCC-CM1 model. The BCC-CM1, 2005 has proved to be very accurate in predicting seasonal climate change as compared to the atmospheric and ocean models.ComparisonAfter the analysis of the two climate models, it is crystal clear that the models were created in the same year and that both of them are coupled employing a combination of two models in one. However, the two models greatly differ from each other. The BCC-CM1, 2005 was designed in China while the ECHAM5/MPI-ON was designed in Germany.

The most important difference is that the BCC-CMI model is very effective in predicting seasonal climate change. On the other hand, the ECHAM5/MPI-OM forecast climate change in the long run (Semenov & Stratonovitch, 2010). The computation of the ECHAM5 is meant to predict the climate change globally, but for a long duration of time. However, the two models are used to measure climate sensitivity, but the BCC-M1 has a higher resolution than the ECHAM5/MPI-OM model (Neelin, 2011).In conclusion, climate change models are very important for forecasting, evaluating, analyzing, and supervising the global climate change.

The models have enabled scientists to study the climate change all around the globe. The BCC-CM1 is used for seasonal prediction while the ECHAM5/MPI-OM which forecasts on a global scale, but for a longer time frame. Finally, the climate change models have continued to be developed as technology changes so as to enhance efficiency and accuracy in climate predictions.ReferencesBader, D. (2008). Climate models.
