Arithmetic Average Method
The contours are plotted on the plans or vertical projection. The area defined is determined by a planimeter or other method. The average thickness is estimated by the simple or weighted arithmetic mean. The average content and the density are determined in the same way. The body part between the inner and outer contour is generally calculated independently because the resources of this area are reported in a lower category.

These winds can exceed speeds of 500 km/h at heights of 1200 m. The name ‘jet stream’ reflects its shape and intensity. There are two jet streams in each hemisphere.
