Supercomputer to improve forecasting of lousy German weather

Meteorologists this week booted up one of the fastest supercomputers in the world to improve German weather forecasting – if not Germany's notoriously bad weather.

The NEC SX-9, which went into operation at the German Weather Service (DWD) in Offenbach on Thursday, should give meteorologists access to highly-complex weather prediction models.

“Thanks to the enormous capacity of the integrated Ensemble [technology] in processing information, this new supercomputer can handle more physics at once, which makes it easier to predict storm cells, heavy rainfall, hail and strong winds than ever before,” said Dr. Gerhard Steinhorst, head forecasting at DWD. “We can also use this information to improve the DWD’s warning system.”

With a capacity of up to 109 trillion multiplications per second, the supercomputer is one of the fastest vector processors in the world. By 2010, it should have improved upon its predecessor’s processing capacity by a factor of 45.

“Ensemble technology can construct as many as 20 parallel forecasts – rather than just one – each based off a slightly different set of starting conditions,” DWD’s Head of System Administration Henning Weber told The Local.

“The overall result enables meteorologists to more accurately determine the likelihood of a particular weather situation.”

But anyone getting too excited about the new forecasting powerhouse should be reminded that it won’t improve the often atrocious German weather likely to ruin your next weekend barbecue.

“The focus with this machine is creating very, very precise weather forecasts for the next 18 hours, in turn allowing city officials to prepare to streets with salt or de-ice planes,” explained Weber. “Three to five day forecasts are something we hope to improve upon in the future.”

‘Turbo spring’: Germany to see temperatures above 25C

Germany is set for a blast of warm weather in the coming week as the colder spell eases off.

'Turbo spring': Germany to see temperatures above 25C

“The late winter weather of the past few days with frost and snow is a thing of the past for the time being, and spring will kick into turbo gear over the next few days,” said meteorologist Adrian Leyser from the German Weather Service (DWD) on Friday.

Temperatures are expected to rise sharply over the weekend with plenty of sunshine, forecasters said. In Germany anything above 25C is classed as a summer day. “The summer mark of 25C will be cracked regionally as early as Sunday,” said Leyser.

It comes as snow and hail hit Germany last week, and temperatures fell below freezing in some places.

But showers and thunderstorms are still possible in the west and north of Germany. Maximum temperatures there are expected to reach around 20C. 

According to the DWD, spring will get a little damper on Monday, with a few rain spells.  “However, the next low pressure system over Western Europe is preparing to turn on the warm air jet again from Tuesday,” said the meteorologist.

On Wednesday – which is a public holiday across Germany for International Workers’ Day – temperatures could soar nearer 30C. 

“In the south and east, we are even approaching the 30C mark,” said Leyser. However, the weather will remain “susceptible to disruption”, said Leyser, especially in the west where there is a risk of isolated and sometimes severe thunderstorms.
