Global temperature change.
Global surface temperature has increased approximately 0.2 degrees C per decade in the past 30 years, similar to the warming rate predicted in the 1980s in initial global climate model simulations with transient greenhouse gas changes. Warming is larger in the Western Equatorial Pacific than in the Eastern Equatorial Pacific over the past century, and we suggest that the increased West-East tem...
متن کاملReconciling Observations of Global Temperature Change: 2013
In 2000 a panel of the U.S. National Research Council in a report with the same title suggested, among other things, that a “substantial disparity remains” between the observed warming rates of the surface and troposphere. Also, in 2000, the climate models showed more warming of the tropical atmosphere than was observed. Many papers have been written since then. We discuss the most recent paper...
متن کاملPrecipitation, radiative forcing and global temperature change
[1] Radiative forcing is a useful tool for predicting equilibrium global temperature change. However, it is not so useful for predicting global precipitation changes, as changes in precipitation strongly depend on the climate change mechanism and how it perturbs the atmospheric and surface energy budgets. Here a suite of climate model experiments and radiative transfer calculations are used to ...
متن کاملEffect of global ocean temperature change on deep ocean ventilation
[1] A growing number of paleoceanographic observations suggest that the ocean’s deep ventilation is stronger in warm climates than in cold climates. Here we use a general ocean circulation model to test the hypothesis that this relation is due to the reduced sensitivity of seawater density to temperature at low mean temperature; that is, at lower temperatures the surface cooling is not as effec...
متن کاملCharacteristic Points of Stress-Strain Curve at High Temperature
Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...
