ABSTRACT

This paper sum up some of the most importand results recently published in Cho & Lindborg (2001) and Lindborg & Cho (2000; 2001). We presents a successful observational determination of the cascade of kinetic energy and temperature and ozone variances in the mesoscale range (~ 1 to 500 km) of scales of motion in the lower stratosphere. The direction and strength of the cascade is determined by calculating third order structure functions using a huge data set (MOZAIC) of wind, temperature and ozone measurements taken from commercial aircraft. It is found that the cascade is downscale, i.e. energy and scalar variance are transferred from large to small scales.
