The UM Rosenstiel School researchers used historical observations of cloud cover as a proxy for wind velocity in climate models to analyze the Walker circulation, the atmospheric air flow and heat distribution in the tropic Pacific region that affects patterns of tropical rainfall.

A large ensemble of Earth system model simulations, constrained by geological and historical observations of past climate change, demonstrates our self ‐ adjusting mitigation approach for a range of climate stabilization targets ranging from 1.5 to 4.5 °C, and generates AMP scenarios up to year 2300 for surface warming, carbon emissions, atmospheric CO2, global mean sea level, and surface ocean acidification.

The underlying integrated assessment model outputs for land use, atmospheric emissions and concentration data were harmonized across models and scenarios to ensure consistency with historical observations while preserving individual scenario trends.

Actual atmospheric scientists know that the historical observations are too sketchy and unreliable to decide one way or another as to whether tornadoes are increasing or not (see this excellent discussion by weather expert Jeff Masters of The Weather Underground).

However, a confident assessment of human influence on hurricanes will require further studies using models and observations, with emphasis on distinguishing natural from human - induced changes in hurricane activity through their influence on factors such as historical sea surface temperatures, wind shear, and atmospheric vertical stability.

Using a state - of - the - art data assimilation system and surface pressure observations, the Twentieth Century Reanalysis Project is generating a six - hourly, four - dimensional global atmospheric dataset spanning 1851 to 2014 to place current atmospheric circulation patterns into a historical perspective.
