Si Fly Flight 3275 were found in good condition. Analysis from the crash site concluded that the plane struck tree tops first before impacting terrain. The first impact occurred 15 metres from the top of a ridge, in a rocky mid-mountain area. During the impact, the fuselage and wing disintegrated, the fuel ignited, and an explosion occurred. The French BEA then collected weather data prior to the crash. From Slovenia to Greece and from Italy to Bulgaria, the winds at altitude were very weak from the north. They were sufficient to create a foehn effect under the mountain winds that left the whole coast
Weather forecasting Weather forecasting Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere at a given place and using meteorology to project how the atmosphere will change. Once calculated by hand based mainly upon changes in barometric pressure, current weather conditions, and sky condition or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric
