Path prediction is essential to prepare for damage caused by typhoons. In particular, in the case of the mid-latitudes to which the Korean Peninsula belongs, typhoons often turn to the right due to strong westerlies made by the Earth's rotation. Depending on the speed of the upper part of the typhoon, irregular routes can be created, and also the temperature of the sea level affects not only the size of the typhoon but also the path. Because of these factors, when predicting the course of a typhoon, the point where the typhoon's eyes move is not marked as a dot, but expressed as a rough "range." 

​

  Using the WRF model data, the location of the minimum sea level pressure is represented by latitude and longitude values. The point is drawn through the ncl function Polymarker, followed by a line using polyline. Next to each point, mark the date and time.

In particular, it is important to change the sea level pressure array to one-dimensional in this process. The time interval was set at six hours. This is because it was judged that dotting every six hours is the most readable.
