Meridian Energy power production

Want to know more about how we’ve calculated Meridian Energy’s power production?


To determine yesterday’s total energy potential from wind, we’ve calculated the amount of power produced by Meridian’s West Wind and Te Uku wind farms, using the observed hourly windspeeds at these locations throughout the previous day. The hourly windspeeds are used to calculate the amount of energy each wind farm is able to produce at those speeds.

The Physics of Fog

By MetService Meteorologist Claire Flynn

While the weather conditions that lead to the formation of fog are usually quite benign, fog itself can be very disruptive. In particular the aviation and marine industries are often interested in how fog or mist will affect the visibility for their journeys, though fog also affects road-users. Fog can also make for some excellent photography opportunities, creating an eerie backdrop (as you can see in some of the photos below!)
