The Basic Aims of ETCE

1. Study the dynamics of the initiation and development of tropical deep convection.

2. Study the generation of stratospheric gravity waves by deep convection. Study the propagation of the waves through the middle atmosphere.

3. Investigate the effects of deep convection on upper tropospheric composition through studies of convec tive mixing and chemical transformations within the convection.

4. Investigate the dynamics and microphysics of the cirrus anvil produced by the Hector convection. Investigate the radiative properties of the cirrus.
