vremea

Asta seara accuw. spune ca sunt 17 grade, dar ca 'real feel' este de 6 grade. Am cautat si iata ce am aflat: "The Real Feel Temperature is something we developed in-house here at AccuWeather. It takes into consideration other factors besides just temperature and dew point. It factors in the time of day, the sun angle, and amount of cloud cover, the winds or lack thereof, etc. For example, a temperature of 90 and a dew point of 70 will feel worse at noon or 1 pm with the sun high in the sky than it will at 5 pm or 9 am. Also, a temperature of 90 and a dew point of 70 will feel worse when it is dead calm than if there is a 15 mph wind blowing. The same thing goes for 90/70 with bright sunshine vs. 50% cloud cover. For all of these examples, the heat index will be identical...no difference whatsoever, since it is based solely on temperature and dew point. The Real Feel Temperature, however, will be different for each case."

foarte tehnic. si pare ca simplica, nu complica lucrurile. prin urmare, daca imi fac un fel de regula pentru imbracat fetita in functie de real feelul lor e mai sigur decat daca ma iau pur si simplu dupa temperatura. dar chiar o diferenta de 11 grade! oare termometrul meu pus afara la ora asta arata ce trebuie?
