Summary
When a point source of (weak) strength ε is placed in a rotating fluid, Barua [5] and Squire [6] described the local effects which exist in a domain of size O(ɛ1/3) about the source. Here we show (a) how this can be joined with the linear solution of Moore and Saffman [8] at distances larger than O(ɛE −1) from the source (E is the Ekman number), and (b) that when the source is placed between two parallel discs, a vortex develops with its axis through the source.
