Study of the development of an extremely high cumulonimbus cloud (Andhra Pradesh, India, September 28, 2004)

Abstract

Development of a cumulonimbus cloud with its top above 18 km in central India is analyzed. The process is observed with a radar. A 1.5 D numerical model is used to simulate the cloud development. The cloud produced very low radar echo, which implies that large cloud particles were absent. Both observations and simulation show that an extremely intense growth of the cloud was associated with its merge with feeder cells. The seeding of feeder cells caused a change in the direction of the cloud movement.

Study of dynamics of the cumulonimbus anvil of large vertical extent

“…Consider in more detail the time evolution of the cloud sizes. The cloud top height obtained from the radar data differs slightly from the real cloud top [3]. The cloud top dependence on time is shown in Fig.…”

“…The detailed data of radar observations of the considered Cb cloud are presented in [3]. Here, a brief outlook of the main results is given.…”

“…The location choice is due to development in this area of long-lasting super-intense Cb cloud which has been observed with the WR-100 radar [3].…”

“…Note that the detailed analysis of conditions for development of this cloud, of its radar characteristics, along with the results of numerical modeling of the cloud, are presented in [3].…”

“…To obtain data on structure and dynamics of the anvils, the satellite observations are analyzed of Cb cloud which developed at September 28, 2004, in India [3]. The location choice is due to development in this area of long-lasting super-intense Cb cloud which has been observed with the WR-100 radar [3].…”
