Hello ladies and gentleman. This is the ambassador of South Korea.

These days, South Korea has been facing series of flight cancellation in Jeju airport. At about January 26^th, due to the heavy snow, all the flights were cancelled for several days so tourists had to stay remain. And just after 16 days, on February 12^th, Jeju airport flight was cancelled again. 56 flights were cancelled, 141 flights were delayed and 17 flights flew back. This time, the reason was strong wind, which recorded the maximum speed of 10.8m/s.

     They say that the causes of this events are turbulence, 'wind shear'. Wind shear which is a meteorological phenomena that wind speed and direction changes abruptly in a short range of time, is generally caused by geological formation. In the case of Jeju island, to simply explain, the wind separates while passing Mt. Halla and combines rapidly, which generates wind shear.

     However, the fact is that this is not just because of the geological problem global warming. According to a study by scientists at the Rosenstiel School of Marine and Atmospheric Science at the University of Miami and NOAA's Geophysical Fluid Dynamics Laboratory (GFDL) in Princeton, N.J., global warming robust increase of wind shear in the tropical Atlantic.

     Though some news states that wind shear is not very related to global warming, I believe that everything is connected in environment. We should always put effort to prevent environmental problems as a part of the Earth.
