Korean researchers have developed technology to help bring about more accurate long-term climate predictions.<br />Park Se-young has more. <br />Radiosondes are carried by weather balloons to altitudes exceeding 35 kilometers above sea level, ...and their sensors measure pressure, temperature and relative humidity.<br />Made up of sensors and transmitters, the instruments are cheap and can be used any time and in any weather conditions.<br />However, measurements can be influenced by sunlight, wind and atmospheric pressure before the instruments reach the target altitude.<br />Korean researchers have developed a new technology that can accurately observe weather by eliminating these external factors.<br /><br />"The pressure, temperature and wind speed all change when the radiosonde is ascending into the atmosphere, and the technology replicates those same weather conditions."<br /><br />The simulation system and temperature control technology can be precisely controlled to create the meteorological elements of the actual atmosphere.<br />The temperatures of the troposphere 10 to 15 kilometers above ground are mostly used for short-range forecasts, …and stable temperatures of the stratosphere are used for long-term climatic predictions.<br />The technology works at altitudes up to 35 kilometers above sea level and in temperatures as low as minus 70 degrees Celsius.<br /><br />"Application of our technology is expected to contribute not only to short-term forecasts, but also in preparation measures to adapt to long-term climate change."<br /><br />By localizing radiosondes, the technology is expected to pave the way for Korea to become a Weather-Ready Nation.<br />Park Se-young, Arirang News. <br />
