I met Dan at a Met. Society conference in November, found him to be very pleasant and enthusiastic. He should get a good reception.
The blocking that occurred at times to the east of New Zealand in December produced an extraordinary month, witrh wet zones in Fiordland and the Alps getting very small rainfalls, while Nelson City had its wettest month since the 1870s. Kotinga, a location near the town of Takaka in Golden Bay, had 1233mm rainfall in December, over half its annual average.
