This blog post is the first in a three-part series discussing verification of MetService forecasts. Here, we present the method used for verifying rainfall in city forecasts, along with some examples.
In 2007 our weather radar network looked like the picture below. The dark part of the circle is the area / range in which the radar is very accurate and the lighter range is useful as a heads-up. New modern radars send out both vertical and horizontal scans allowing us to not only determine the presence of rain but the volume as well. This is really handy for forecasting and tracking storms and severe weather.

During the approach to summer, eastern parts of both islands will get more warm Foehn winds under suitable conditions. In this blog post I'll describe what the Foehn wind is and explain how it comes about. We'll start by looking at temperature reports from weather stations on Saturday 16 Oct 2010.

A recent visit to Sydney International Airport has inspired me to write a little about another famous aviator with a New Zealand connection. Last year I wrote a post about Jean Batten who, in her youth had met the topic of this post, Charles Kingsford Smith. Auckland International Airport is named in honour of Jean Batten and likewise Sydney International Airport is named after Charles Kingsford Smith.
These clouds show waves rolling along and breaking in the sky, similar to the way that waves behave on the sea.
