We used an average of the road surface temperature measurements within 50 m of the road weather station during a pass as the road weather model initialization value.
"Based on our weather model outputs, Yutu will not make landfall in the country but it is still possible that it will change its direction," Rojas said in Filipino.
Nowadays, a weather forecast typically consists of multiple runs of a weather model. Operational weather centres usually run a global model with a grid spacing of around 10km, the output of which is passed to a higher-resolution model running over a local area.
A weather model analysis showed that Monday's temperatures over southern Pakistan were up to 25 degrees warmer than normal.
"It's like the raw compressed power of 100,000 home computers at your fingertips," said Senior Airman Jeffery Niles, a weather model software technician assigned to the 2nd WXG.
When the storm is in this stage, forecasting an accurate path is hard as herding cats, regardless of the weather model, despite the availability of live data from so many reliable sources, such as temperature, humidity, wind speed, air pressure as well as water temperature and salinity of water - and at multiple levels of the atmosphere.
As the predictive weather model developed by UConn and PSU matures, Eversource will share the information with other utilities, he said.
For example, their new Cray XC40 will allow the Australian BOM weather model to move from a 4-km to a 1.5-km grid.
Weather model data compiled by Masdar University of Science and Technology looks at the impact of climate change on weather patterns in the UAE.
The researchers will then combine this data with a large-scale numerical weather model to understand the atmospheric transport of the gases.
"The tropical storm is expected to weaken before approaching the coast of sultanate of Oman", the NCMS said, adding that the weather model charts don t show any direct effect to the United Arab Emirates in the next four days.
