Meteorologists warn some of the 5G frequencies could interfere with water vapor signals, meaning less accurate weather forecasts


Wireless radio frequencies being auctioned by the U.S. government for mobile 5G networks could interfere with weather forecasts and make them much less accurate, as the mobile network could cause interference that prevents satellites from detecting concentrations of water vapor in the atmosphere accurately, warn meteorologists. A new global problem.

For months, the National Oceanic and Atmospheric Administration, NASA, and two committees in the U.S. House, asked the Federal Communications Commission to delay 5G spectrum auctions.

But the FCC has gone ahead with the sales. An auction on April 17 involved two groups of frequencies: one between 24.25 and 24.45 gigahertz and the other between 24.75 and 25.25 gigahertz.

Water vapor problem

Information about atmospheric water vapor is plugged into computer models to predict how weather systems will behave. The vapor transmits a faint signal at a 23.8-gigahertz frequency.

Meteorologists say a 5G station transmitting close to that same frequency could be mistaken for water vapor, and, they warn, that could make forecasts less accurate.

This is the first time we’ve seen a threat to what I’d call the crown jewels of our frequencies — the ones that we absolutely must defend come what may,” Stephen English, a meteorologist at the European Centre for Medium-Range Weather Forecasts in Reading, UK.

Brian Donegan, a meteorologist, said, “Five-day hurricane track forecasts are more accurate today than two-day forecasts 25 years ago. I would hate to see these vast improvements take a major step backward, especially after the active 2017 and 2018 hurricane seasons the United States just endured.

No auction delays

In March, three chairmen of U.S. House Appropriations subcommittees sent a letter to FCC Chairman Ajit Pai asking him to delay an auction that month.

Without this data, the nation’s forecasting capacity would be reduced to the accuracy of the forecasts produced in the 1970s,” the Democratic congressmen wrote, according to Roll Call. “For example, the forecast for Superstorm Sandy would have predicted landfall in Maine 24 hours later than actual landfall occurred in New Jersey, roughly 300 miles away. This would have further imperiled millions of Americans.

The letter was written by Peter J. Visclosky of Indiana, chairman of the Subcommittee on Defense; Mike Quigley of Illinois, chairman of the Financial Services panel; and Jose E. Serrano of New York, chairman of the Commerce, Justice and Science subcommittee.

A similar request was made by Texas Democrat Eddie Bernice Johnson and Frank Lucas, an Oklahoma Republican, who lead the House Science, Space and Technology Committee.

Given the frequency spectrum being considered, and at the FCC’s suggested noise limits, there is the potential for signal interference with Earth observation sensors for weather and climate forecasting which operate at adjacent spectrum frequencies,” the letter said, according to Space News. “We are therefore asking you to delay the auction of 5G spectrumuntil NOAA, NASA and the (Department of Defense) have been adequately consulted and their concerns have been addressed.

The Trump administration has been a proponent of rolling out 5G networks faster. At a White House event on April 12, President Donald Trump said 5G networks will “transform the way Americans work, learn, communicate, and travel. 5G networks will create astonishing and really thrilling opportunities for our people.

5G networks are expected to be at least 100 times faster than the current 4G networks, cut delays and allow for innovations in a number of fields.

5G wireless technology is not only dangerous for your health… It could lead to more dramatic natural disaster events. Get ready! Be prepared!

  1. How people dont see this amazes me.
    Every home has a microwave…very similar. Obviously 5g will act the same the point of the problem is it will evaporate water quicker i suspect far more tornados and disruption of natural wind currents.
    Ima post you page on a site. Little curious bout the natural evaporation rate with these systems some serious weather could be caused by it. But it could also be used to stop bad weather. One thing … dont play with nature everyone knows that rule. Most likely increased lighting bolts as ive seen for a while. Since 2g 3g 4g.
