Abstract

The meteorological conditions leading to the appearance of a parhelion at Calcutta, accompanied by a partial halo have been investigated. From the angular elevation of the sun, the distances from the sun of the parhelion and the partial halo at the times of their appearance and disappearance have been computed. The study leads to the Inference that Incipient cirrus is mainly composed of hexagonal Ice crystals with their sides vertical in a field of light to moderate winds. The distribution of such crystals is orderly and the deviation of light through them is a minimum.
