One of the best ways to reduce the likelihood of Covid-19 being transmitted in Aotearoa New Zealand classrooms is simply by opening doors and windows to create natural ventilation, say NIWA air quality experts.
The NIWA and MetService assessment of named tropical cyclone (TC) activity indicates 8 to 10 named TCs could occur in the Southwest Pacific basin between November 2020 and April 2021. This seasonal outlook is for normal to below normal activity in terms of overall named cyclone systems in the region.
Rainfall is about equally likely to be near normal or below normal in the west of the South Island, about equally likely to be near normal or above normal in the east of the North Island, and most likely to be near normal in all other regions.
Oceanic ENSO-neutral conditions will very likely persist over the next three months. The long-standing climate drivers that have contributed to dryness over much of NZ are expected to influence our weather for at least the first half of the winter season.
For more than a century, a network of volunteers across New Zealand have been measuring the climate and weather and sending their observations each month to be entered into the New Zealand climate database.
