A better understanding of the mechanisms important in the production of the forbidden O I green line feature in meteor wakes may result from a theoretical approach to the relevant dynamic and reaction processes in a plasma column. A model is develope

A VHF doppler auroral radar operating in the south of New Zealand since early 1978 has quite frequently observed long persisting echoes with large doppler shifts over a limited range interval. These are confined to dark hours, are primarily in the pr

The method of Jones used for the ray tracing of internal gravity waves has been applied to radio waves in the ionosphere. This method avoids problems usually encountered near a reflection point and, consequently, may be used to trace both reflected a

Summary Extensive F-region ionospheric disturbances were recorded at the New Zealand ionospheric stations at Rarotonga, Christchurch, and Campbell Island followingthe Johnston Island nuclear explo5ions. From these records, as well as from magnetic re

The air-glow ermssions were associated with an electron cloud in the F region over Christchurch, New Zealand. The cloud seems to have been formed by the influx of exospheric plasma, the air-glow emissions being excited by secondary electron impact. E

An attempt was made to estublish some of the theorems necessary for the extension of the Chapman theory of layer formation to the case where a spectrum of ionizing radiation acts on an atmosphere with any temperature profile. Some invariant propertie
