Climate developments in February 2002
Active convection over equatorial waters about and west of the date line Low rainfall in the Northern Cook Islands and much of French Polynesia
An extensive area of enhanced convection occurred over equatorial waters about and west of the date line, from Papua-New Guinea to Eastern Kiribati, with another convective band associated with a southward displacement of the SPCZ extending from Tuvalu southeast across Fiji and Tonga. Rainfall was at least 125% of average at many locations within these convective regions, but more than 200% of average in some northern and central areas of Fiji and southern Tonga. Rainfall totalling more than 400 mm was measured at Fua'amotu, Tonga from 18 to 22 February. It was extremely wet in Rapa, southern French Polynesia, due to high rainfall (over 400 mm) during the last week of the month.
