The condition of upper atmosphere is investigated with relation to cyclones. The strongly deepening cyclones are associated with the typical westerly troughs which have a characteristic structure. On the other hand, cyclones can hardly develop in some period. The northward displacement of cyclones is remarkable in front of a typical westerly trough and is related to the distribution of westerly wind velocity.
