NASA photo shows where Hurricane Michael turned out the lights

The new NASA image shows that when Hurricane Michael falls on the Florida strip on October 10, Arash blocks some of the roads in Florida and Georgia. These pictures clearly remind us that the energy infrastructure is vulnerable to natural disasters.

The photo was released today at NASA's Earth Observatory Blog, but since the "post" image was taken on October 12th, the light began to open again. According to data from the Edison Power Research Institute, the number of customers not receiving power has decreased from 6 million electricity after the occurrence of hurricane to 163,000 electricity. (It is clear that this figure reflects the number of people, not reflecting the number of meters that do not have electricity, which may be higher.

NASA 's Earth Observer says it may have to wait weeks or months to fully repair the grid to recover power. For people it takes a lot of time to power the refrigerator, charge the medical equipment, and drive the air conditioning equipment.

So do not bundle them only to be blown away by the strong winds, but please fill their transmission lines in areas where hurricanes like Florida are likely to occur. According to the US Energy Information Agency, last year, after the attack of Hurricane Ilma, Florida's 7 million power customers failed. This is almost two-thirds of state customers.

This is a problem and I am researching Ted Kury, director of energy research at the University of Florida. The answer: It is complicated, he writes in Dialogue's article. Of course, laying power lines underground can protect them from the wind, but it also increases the risk of storm surges and floods that could damage the wires. In addition, placing the wires underground is expensive and can be more difficult to enter the power line for repair.

Electric power companies need to compare more mainstream strategies, such as to keep the strengths and strengths of underground circuits and strong winds from pushing trees to power lines. As climate change increases the intensity of hurricanes, the calculated risk continues to increase

Picture: Hurricane is moving with power. The air pressure at the edge is higher than the center air pressure, it creates a force towards the center centripetal force and rotates the air at high speed. This picture shows where Hurricane Franc travels to North Carolina State and Virginia State in August 1989; it continues to cause losses of around $ 5 billion. The picture was provided by the House NASA. Look closely at what you are turning, you will always find centripetal force, it is spinning somewhere. When your clothes roll in a washing machine it gathers a lot of water, so it must be removed when it last spins. The drum of the washing machine rotates at high speed, always pushing the clothes into the circle, giving the centripetal force to continue to rotate. Water in the clothes pushes the fiber. It can not be held in place - there is no centripetal force - therefore it scatters by rotating the hole on the outside of the roller to help dry clothes.

NOAA 's GOES - 13 satellite captured the visible image of the attack Hurricane Sandy attacked on the east coast of the US at 9:10 AM Monday, 29th October, showing the scale of the storm. Images were created by NASA's GOES project at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The strong wind of tropical storms grows about 500 miles from the center and the diameter is about 1,000 miles. Infrared satellite images provide predictors with temperature data to identify cloud heights and intensities in various parts of the storm. Basically, the higher the cloud top, the lower the temperature and the stronger the storm. The strongest storm may have the most precipitation.
