Introduction: Since there are not many organized search, statistics, and information about understanding storms, the present research aims to study and review the storms in Khorasan province with the target of prevention and preparedness.
Methods: Reports of 18 stations were used in this study including reports of synoptic stations in the south of Khorasan, and data of 3 stations in the west of province such as Birjand, Posht Badam and Tabas in 2003. Data of speed and direction of monthly winds were collected in different years of Meteorological Organization since its foundation. The number of dusty days, absolute temperature, and average monthly minimum temperature in stations were also collected and data was analyzed.
Findings: Wind speeds in the center of the province were less than northern, eastern, and southwest due to high mountains. According to the studies, the high-speed winds were in different directions but in some directions had higher frequency.
Conclusion: The speed of fast winds would cause financial losses and casualties. Since the probability is relatively high, it should be considered as a serious threat.
