OROGRAFİK (YERE-YAKIN) ALANLAR ÜZERİNDE ZAMANLA HIZLI DEĞİŞEN 3 BOYUTLU RÜZGAR GİRDAPLARI VE BUNLARIN UÇUŞ GÜVENLİĞİNE ETKİLERİ
In this study, it is studied that the augmented Wind-FLOWER numerical modelling skill’s applications and
land-surface (orographic) air flows’ numerical modelling on mountain areas by using real topography datas
which are defined on geographic areas. This numerical modelling skill’s simulation results show that 3-D
specifications are very important for being of time-dependant quick-change vortex which are included by landsurface
air flows. In the numerical modelling skill’s applications topographical numerical altitude datas that
include informations and datas of really “Numerical Altitude Model (NAM)” are used. These real topographic
datas, used in application part, are examinated very tightly and seperated same size topographic datas before
using as initial/beginning datas for Wind-FLOWER numerical modelling. Then, these topographical datas are
used as land-surface data for modelling applications. This modelling applications include a pro-precessor and a
post-processor. The pro-precessor runs land-surface numerical datas and uses them in numerical modelling
applications. The post-processor constitutes 2-D and 3-D images by using the numerical modelling applications’
datas of land-surface air flow and determined vortex formations and vortex-density distrubitions. Furthermore, a
“Graphical User Interface (GUI)” is constituted which is required to work with pre-processor and postprocessor
and is practiced for easy usage of numerical modelling.
