Cyclone Idai Case Study - Internet Geography
The frequency of TCs that affect Korea is low high in a year of summer drought non-drought. As a case study, in when there is extremely severe summer drought in Korea, there was high frequency of TCs while in when there was least severe summer drought, the frequency of TCs is the lowest. Changes in the anomalous secondary circulation, namely anomalous upward downward flow in the SWNP and anomalous downward upward flow in the mid-latitudes of East Asia, are one of the causes of drought non-drought. In the summer of , East Asia in particular, the southern part of Korea, middle China and Japan went through the severest drought in 30 years WMO Park and Shubert argues that the drought in was caused by two factors: one is the early development of East Asian high caused by the abnormal development of the Eurasian wave coupled with the Tibetan Anticyclone and the other is the failure of influx of water vapor derived from western Pacific and Indian Ocean due to strengthened cyclonic circulation in the subtropical western North Pacific SWNP.

The magnitude of the divergent component of the wind is relatively small compared to that of the nondivergent component in large-scale atmospheric flows; nevertheless, it plays an important role in the case of explosive cyclogenesis examined here. We have calculated the kinetic energy budget for the life cycle of an intense, developing cyclone over North America. The principal kinetic energy source is the net horizontal transport across the boundaries of the region enclosing the cyclone. By investigating the relative importance of the divergent and nondivergent wind components in the kinetic energy budget, we found, as expected, that neglecting the divergent wind component in calculating the magnitude of the kinetic energy is of little consequence, but that the horizontal flux convergence and generation of kinetic energy depend crucially upon the divergent component.
