The process of monitoring and analysis of the totalitarian and climatic conditions that have synchronized the appearance of the Tornado in fact has Left beside.

This research paper is done for documentation of the existence of that phenomenon which is unfamiliar and even unprecedented in the weather of Iraq.

The researcher relied on the analysis of the synoptic charts of the region in which Tornado was acquired and in a sequential form by analyzing the area maps before the hurricane’s day, during the day of the hurricane and then the day after the hurricane.

The wind speed varied between (110-86) miles per hour.

The researcher found that the reason behind the hurricane was due to the control of a warm and moist air mass on the surface, while another cold air mass was controlling the linear level between (700-850) Hectopascal.

Because of this, there was an air disturbance in the attempt to rise the wet and warm air up as it has been near to the cold air, and that in fact helped for the appearance of the Cloudy clouds
