New method to forecast tsunamis

Now predict tsunamis, storms and tornadoes will become easier work than before.Russian Physics-Meteorologists successfully simulated the process of producing a natural disaster in laboratory conditions, a unique series of physics-meteorological complexes.

The Institute of Applied Physics at the Russian Academy of Sciences in the Volga city of Nizhny Novgorod created a tropical storm. Naturally, storms in experimental conditions. A large-capacity blower through the filtration system begins to draw air into the water tank where the pilot equipment is installed.

Test "re-show" the storm in the South Ocean. Wave wind is a large pipe with a length of 10 meters. Under plastic rotors, simulating a storm with crazy power, wind speed of up to 40m / s. The wind blew like that in the storm 'Sandy' that attacked the United States last October and divided Manhattan and the mainland. Another terrible example of the devastation of natural disasters is the tsunami caused by the Indian Ocean earthquake in December 2004, killing hundreds of thousands of people. Finally, in the human memory, there is a vivid image of the devastating earthquake in Japan in March 2011, accompanied by a shocking tsunami and a serious accident at the "Fukushima" nuclear power plant.

The storm created in the laboratory physical-geo-model similar to natural storms to the extent of "perfect" . Water tank area as a miniature part of the ocean at a ratio of 1: 100. All events in the wind-wave channel are recorded with a special video camera with a speed of receiving 8000 frames per second. "We are interested in the process of creating eruptions, forms on the sea, which is a way to measure the waveforms generated by wind power , " - researcher Aleksandr Kandaurov from the Institute of Applied Physics said.

Scientists study the process of creating water walls, how waves on the sea surface appear and resonate with atmospheric pressure and produce storms with destructive power. The "artificial" storm is the key to unlocking the mysteries of natural disasters.

It seems that scientists are clear now, the reason why giant waves don't turn off the wind speed. Physicists attach this phenomenon to the "smooth surface mechanism ." The wind merely "cuts" the top of the big waves thanks to the intense aerodynamic pressure.

The laboratory equipment in Nizhny Novgorod is unique, nothing similar in the world. The cooling system and heat pump create the same temperature range as in the real Southern Sea. Even American colleagues acknowledged this superiority.

In the calculations of scientific experts at the Institute of Applied Physics using meteorological data. They analyzed all data and applied it to the results of experiments to create geophysical models. Scientists expect that a complete algorithm will be created, allowing accurate predictions of how the storm is forming, where, with how much speed and the metamorphosis scheme on the path of travel. hurricane.
