In this study, we have focused on severe weather hazards affecting safety in aviation. We have studied and emphasized on the weather patterns that leads to the mentioned weather hazards. During this work, it is analyzed on how the major weather hazards affects aircraft structure, operations and passenger life. Weather is unpredictable with the current technology and tools. In most cases, weather has to be avoided for safety in aviation and hence accurate prediction is demanded. With the use of future weather technology models, integrated with AI and Machine Learning, weather prediction would be precise and timely.
