The Foehn Wind

Last Saturday many parts of New Zealand, especially South Island, experienced Foehn winds. As summer approaches 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.

Challenges in forecasting severe weather

The severe weather in various parts of the country over the last week or so has presented a significant challenge to some communities – and to staff at MetService as well. Getting the message out about severe weather, particularly when it involves rapid changes, requires excellent communication with the New Zealand public and many organisations managing weather-related risks. The message needs to be relevant and clear – not always an easy task, given that users of weather information have such diverse needs.

Wave three

New Zealand has been in a strong west to southwest flow for a few days now. This weather regime looks as though it will continue for the next few days.

There are reasons why the weather gets into regimes like this. It has to do with what meteorologists call the "long waves".

Going Viral

A story titled "Massive storm heading for New Zealand" went viral in the online media overnight Wednesday 15 September.

Charles Kingsford Smith

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.  

Breaking waves in the sky

These clouds show waves rolling along and breaking in the sky, similar to the way that waves behave on the sea.
