More rain in Australia due to La Niña

Currently there is a period of La Niña (a coupled ocean-atmosphere phenomenon oposite to El Niño) which means the sea surface temperature across the equatorial Eastern Central Pacific Ocean will be lower than normal by 0.5 °C. This basically means that Australia will be wetter (more rain) during a period of El Niña. La Niña is often preceded by a strong El Niño, the latter being famous due to its potentially catastrophic impact on the weather along both the Chilean and Australian coasts. According to the model outlooks for El Niño and La Niña the La Niña has weakened which may be good news for all Aussies: good weather is coming! ;) (but so may the draught :S)


Normal Conditions

Normal Pacific pattern. Equatorial winds gather warm water pool toward west. Cold water upwells along South American coast (the North East Australian cost is visible in the lower left corner of the map above).


El Niño

El Niño Conditions. Warm water pool approaches South American coast. Absence of cold upwelling increases warming.


La Niña

La Niña Conditions. Warm water is further west than usual.

Springtime

As of 6:48 this morning it’s spring :) All over the world day takes as long as night as the sun is now positioned exactly above the Equator. The Northern Hemisphere is now on it’s way to summer. For Australia (and the other countries in the Southern Hemisphere) it is exactly different as now it’s Autumn Equinox over there so they are moving to winter. Which means I will be traveling from early spring into early autumn. Lucky for me Australia lies in more tropical regions than Europe ;)

In adition to the start of spring, I just got an SMS message forwarded that a friend from years ago (who is now living in Wellington, NZ) just got a son: Nolan Huia van Proosdij; congratulations mate :)
