Weather balloons - Tetroon balloons?

UFO is the famous word for any aerial appearance whose purpose cannot be simply or promptly identified by the eyewitness.

Some have established that the greater number of UFOs are experience of some real but standard thing-most commonly aircraft, balloons, or astronomical objects such as meteors or bright planets-that have been mix up by the eyewitness as abnormality while a little percentage of reported UFOs are fraud.

Nevertheless a Tetroon Balloon cannot be discounted as one of the Unidentified Flying objects.

The Tetroon is actually a tetrahedral balloon adopted for horizontal sounding. It was made to take the highly low pressures of high-altitude aviation; the straight seals joining its four triangular faces are robust than the curved seals of the more normally shaped balloons. Tetroons have been used broadly in tracing low-level atmospheric currents by observing their movement with radar; they have thus increased the meteorologist's knowledge of atmospheric turbulence, low-level vertical motions, and air pollution dispersion.

A pilot balloon which acts the same as ceiling balloon but can be used at night. A sounding balloon is the counterpart of tetroon balloon but is not used as high altitudes as tetroon balloons are deployed.

Now we may envision that balloons are ordinarily used at parties or at carnivals. More importantly they are actually utilized by meteorlogists. Which at any single day, about 800 locations worldwide releases off balloons. Some of these are weather stations or meteoroligist laboratories monitoring the weather conditions in their respective countries. Most even deploys weather balloons many times a day to make sure weather state on locations which may be very erratic.

Tetroon balloons can be seen all over and sometimes be taken into account as a unidentified flying object yet they play a very important role in getting data of weather conditions the world over.
