Understanding the patterns of flying patterns that govern air traffic is important for reducing the challenges of the aviation industry. In order to identify the circulation patterns effective in creating flight disturbances, data from sea level pressures and 500 and 850 hectares in the geographical range of 0 to 80 degrees east longitude and 0 to 80 degrees north latitude as well as atmospheric atmospheric parameters, specific humidity and Ordinary and meridian components of the wind were selected based on the days with more than 8 airway disruptions and low visibility horizons in the months and the related maps were drawn in the Grads software environment. The results show that effective circulation patterns in flight disturbances in January of the cold season have low compression system at sea level, high-altitude wake-up system at 850 hectares and heights at high altitudes of 500 hectares, the Mediterranean Sea, the study area . In a roundabout pattern, the geopotential height of 850 hPa was formed by a planetary low-level system formed on the area. Is. At a level of 500 hectares, the high-altitude deployment of the area affects the area. Generally, the height and height of the junction, at 500 horsepower, and the rotational flow at 850 hPa, along with the rule of the heat shrinkage on the surface of the earth, show the harmonic arrangement of summer patterns during the warm period of the year.
