A study led by UC Riverside (UCR) atmospheric scientists predicts that unchecked carbon emissions (排放物) will force tropical rains to shift northward in the coming decades, which would profoundly impact the regions near the Earth's equator.
The northward rain shift is caused by complex atmospheric changes. These changes are driven by carbon emissions, which in turn influence the formation of tropical convergence (汇集) zones. Those zones are essentially atmospheric engines that drive about a third of the world's rainfall, which Antony P. Thomas, a professor of climate change and sustainability at UCR reported in a paper published in the journal *Nature Climate Change*.
Tropical regions on either side the equator, such as central African nations, northern South America, and Pacific island states would be the most affected. Major crops in these regions include coffee, cocoa, palm oil, bananas, sugarcane, tea, mangoes, and pineapples.
Tropical rainforests can have as much as 14 feet of rain a year. "The rainfall change is enormous," Antony said. "It's a very heavy rainfall region. So, a small shift will cause big changes in the economy of the societies. It will affect many regions."
Antony and his colleagues used advanced computer models to predict the atmospheric influence of carbon dioxide emissions from continued burning of fossil fuels and other sources. "This climate model included many components of the atmosphere, ocean, sea ice, and land. All these components are interacting with each other," he said. "Basically, we try to simulate the real world. In the model, we can increase our carbon dioxide emissions from pre-industrial levels to much higher levels."
The analysis accounted for how carbon emissions influence the amount of radiant energy at the top of atmosphere. It also considered the changes in sea ice, water vapor and cloud formation. These and other factors resulted in conditions that push the rain-forming convergence zones northward by as much as 0.2 degrees on average.
