Application Of Simple Wind Model For Weather Modification Activity In Indonesia

Endarwin (1)

Weather modification activity in Indonesia to overcome drought effect or to accelerate condensation to produce rain, usually is worked every year especially in transition period between rainy season and dry season or the opposite. One of the important factor that can support this activity by using of simple wind model that can give the information about the atmospheric condition especially about the possibility of growing cloudy area (cloudy potency) and atmospheric instability in micro until meso scale area with analog analysis. By this model, the limitation of upper wind data spreading as a consequence of limitation number of observation points can be overcome without spend high cost with good accuracy. By this model, the meteorologist can give suggestion or decide where the flight engineer should spread the salts that brought from land to the air by an aircraft. So that the effectiveness and the result will be better. To develop this model is needed minimum number of upper air observation point that can coverage or representatively for all area will be managed. So that usually provided at least 4 points observation that located in irregular place of all area. From 4 points, can be increased become 5 or more, depend on the necessity by interpolation after pass the scalar processing. The interpolation method that will be used is Kriging Interpolation Method that can interpolate the scalar value in irregular to irregular place or from irregular to regular place. In this chance will be develop the new value from irregular to regular place in grid shape. That is from 4 points in irregular became 80 points in regular position. So from this result the wind condition in the atmosphere can be viewed clearly and easier to be analyzed. And Finally determination of cloudy potency area and instability area base on wind pattern in every layer can be worked accurately.
