摘要： PROBLEM TO BE SOLVED: To accurately predict the state of occurrence of sandstorms and issue a warning on occurrence of sandstorms.
SOLUTION: The presence of rain at an area of an object of prediction is predicted and judged (S21). In the case that the presence of rain is predicted, it is judged that sandstorms will not occur. When the absence of rain is predicted, a wind velocity threshold value corresponding to a sand shape of the area of an object of prediction previously stored in a sand shape data storage part is read (S22) and compared with a predicted wind velocity (S23). When the wind velocity is less than the threshold value as a result of comparison, it is judged that sandstorms will not occur. When the wind velocity exceeds the threshold value, it is judged that sandstorms will occur, and an alarm is issued (S24).
