Forecaster makes bold weather prediction for rest of year
Whatever happens on the sun affects us on Earth.
This was the message veteran forecaster Hayden Walker delivered to packed crowd at the Wooroolin Town Hall on September 6.
Brought to town by BGA Agriservices Mr Walker talked about the methodology he using to predict weather months and even years in advance.
Instead of using traditional methods Mr Walker compares a region's barometric pressure with historic trends and the suns current magnetic field activity.
He claims that as sun spots and solar flares develop they project a magnetic field that affects our atmosphere, forcing clouds to build and release their moisture or dissipate without any rain.
"Sun spots fuel low pressure systems," Mr Walker said.
"If you have a low pressure system building and the sun spots start increasing in size and strength than the low pressure system will grow, form a trough and cause a lot of rain."
Like our weather on Earth, sunspots and solar flares have a natural rhythm forming at the poles before growing stronger as the move towards the sun's equator.
They vary in size from 16km to 600,000km in diameter.
While sun spots are cooler than the rest of the sun's surface they emit a lot more radiation.
Mr Walker said that when the sun spots are at their largest we get drenched with rain.
He said he forecast the 2010/11 floods and that all of the major flood events over the past 100 years were preceded by period of excessive sun spot activity.
Though not as extreme as the summer of 2010, Mr Walker said we are entering a similar period meaning we're in for some wet weather.
"In November we'll see between 400 and 600mm fall on the coast and about 100 to 200mm fall inland around Kingaroy."
This higher than average rainfall will continue up to March with dry harvest months predicted for April and May.
Mr Walker said all predictions are vague when cast so far forward but he maintains that he has a 75% accuracy rate.
Given that everything on earth is made of charged atoms Mr Walker said there could be some truth to the old farmers myths about the presence of black cockatoos, ants moving inside and a goannas walking backwards as signs of rain coming.
"The animal kingdom reacts to the atmosphere, we're all made of pluses and minus and when those extremes get going something is about to happen."
