Teploothody of large cities can affect the climate

January 29, 2013. Heat from buildings, factories and cars in large cities may have an impact on the climate at a distance of several thousand miles away from these settlements. "Teploothody" disrupt operation atmospheric systems, which can lead to an increase or, conversely, a decrease in seasonal temperature within one degree Celsius.

This effect may explain why winter temperatures in some parts of the northern hemisphere are higher than expected. The findings of scientists, led by Dr. Guang Zhang of the name of the Scripps Institute of Oceanography in California published in the journal "Nacho klaymat chendzh."

According to the researchers, some of the most populated cities and energy are at high-altitude jet streams in the atmosphere. One of them is called the polar and "teploothody" caught up in this movement, and just could contribute to winter warming in the northern regions of North America and Asia.

In addition, experts have analyzed the consumption of energy in the world. In 2006, the figure was 16 terawatts, or 16 trillion watts.

Earlier we quoted opinion of the representative of the National Climatic Data Center (U.S.) Paul Groisman, who argues that the snow that fell on Europe and Russia at the end of 2012 — the beginning 2013 , may be due to a record decline in ice area Arctic. In other words — the more ice melts in Arctic, become even more severe winters on the continents.
