Will 5G impact weather forecast?
Will 5G impact weather forecast? Recently, when the storm came, the accurate prediction of it had come in time. Meteorologists fear that they may have difficulty after 5G. The frequency of the telephone system hinders the satellites providing weather information.
One of the information on which the incoming weather is detected is the amount of steam in the atmosphere. It is the invisible water which is present in the atmosphere in the form of gas in the form of steam. When it cools, a cloud first forms and then causes rain. The satellites of the European Space Agency and the American NASA keep measuring it. Other countries including India have also sent their satellites to space to get weather information. The most important thing for meteorologists is that they can make steam visible. If they know its quantity then you can predict exactly when and where the storm or cyclone is going to come.
If they do not know the amount of steam properly, then the place of prediction can be up to 100 kilometers away. The estimated time of warning may also be wrong due to which the lives of people may be in danger
What is 5-G Technology
In Mobile communication or telecom sector, 5G is the fifth generation technology standard for communication of broadband cellular networks, many cellular phone companies began deploying worldwide in year 2019, and are the planned successor to the 4G – forth generation networks which provide connectivity to most current cellphones.
The amount of vapor in the atmosphere
Vapor in the atmosphere is measured with the help of weather satellite sensors. Its essential information is sent through a very weak microwave signal at frequencies of 23.4 to 24 GHz.
Clemens Zimmer, a professor of meteorology at the University of Bonn, says, “Waves are produced by small changes in the speed of the vortex. Its center is at 22.235 GHz. These emissions differ from the heat emitted from the stove. No. But we measure it on a scale of centimeters. “
The problem in this is that the International Communication Union ITU has decided that the 5G network will send signals at frequencies from 24.25 to 27.5 GHz. With this, there will be a difference of only 0.25 GHz in the frequency of the signal required for the prediction of the mobile phone network and the weather. Because of this, it is certain that the mobile phone’s antenna and the phone will obstruct the work of meteorologists. Also because the vapor signal is very weak. “There is very little change in temperature in the vapor molecule, so it is difficult that even the slightest obstacle confuses the sigmal,” explains Zimmer.
Still meteorologists feel that other signals are entering their area. For example, a satellite of the European Space Agency at 1.4 GHz measures ground moisture and salinity at the top of the ocean. Pro. Says Zimmer, “The wetter the ground, the less energy it will reflect. It can be measured and also used for weather forecasting.”
Effect on environmental monitoring
To reduce obstruction in the work of weather satellites, the World Meteorological Organization has been advised to reduce the capacity of the transmitter. In this way the transmitter can transmit up to a maximum of -55 decibel watts in the tower neighborhood. This is equivalent to a transmitting capacity of 10 microwatts. But the advice of meteorologists was turned down. They set its limit to 33 decibels, which is equivalent to 1 millivot transmitting capacity. This limit will be applicable from 2027.
Pro. Zimmer fears that it will be too late for meteorologists by then. Especially in the time of implementation of 5G, there is a concern that the market can get cheaper and not be able to transit properly. If the vapor information of meteorologists is lost, it will also have an impact on the research being done about the environment. Pro. Zimmer says that since 1980, satellites have been operating at this frequency, and if not, it will have an impact on environmental monitoring. For 30 to forty years this frequency is being used to monitor the weather. Source by DW.com
If meteorologists lose in the process of implementing 5G, then future high frequencies will also be at stake. But the World Meteorological Organization, along with the national meteorological departments, is still engaged in its efforts. Read More About Science and Technology
