The index combines temperature and wind to estimate how cold it feels.
Commercial aircraft are used routinely to collect atmospheric data temperature and wind data.
Depending on a variety of factors including temperature and wind, wildflowers usually appear in Anza-Borrego between February and April.
When they reached it, they realized that it was a meteorological instrument recording such data as temperature and wind speed.
New this summer is an interactive Mars exhibit, sure to fire kids' imaginations with 3D displays and simulated Martian gravity, temperature and wind.
"The humidity level's a big factor," Mr. Tauber said, "and a combination of that, air temperature and wind direction, makes it feel not as bad as it is along the coast".
They said no one knew what drove the cycle of warming and cooling in the North Atlantic, and the relationship between the water temperature and wind shifts was being studied.
The speed, density of ash cloud, size of ash particles, temperature and wind all have an impact – in short there are just too many variables and it's extremely difficult!" Does ash affect the fuel efficiency of an engine?
It could, he said, produce the same result for a day at noon in the sun in downtown New Orleans or a night on a beach, as long as temperature and wind were the same.
The RealFeel, Dr. Myers said, takes into account eight parameters -- not only temperature and wind, but also "precipitation, cloudiness, density of air -- all the factors that affect human comfort".
They used data provided by the British government for 2005 and simulated temperature and wind fields using a weather research and forecasting model similar to those used to predict short-term weather.
