What determines the feeling like a temperature?
Often the learning of expected high and low temperatures is not sufficient to prepare for walking outside. Many people are waiting for hearing feel like a temperature before they plan to wear and where to go on a given day. This temperature gives people an idea of how they will feel outside, rather than a simple temperature that lets them guess. To determine this temperature, meteorologists must take into account factors such as wind cold and heat index. Wind cooling includes temperature measurement as felt on the skin that is determined by air temperature and wind speed. In other words, it is the degree of thermal skin when the wind blows. Wind cooling is usually always lower than the air temperature, because the wind increases how quickly the moisture evaporates from the skin and serves to move the heat from the body. High -temperature ER, wind cooling is considered much less significant and usually do not report.
thermal index takes into account how heatThe air, so humidity in determining how warm temperatures feel for the person outside. When the individual sweats, the water in his sweat evaporates. This helps to cool the body because the heat is transferred during evaporation. When the moisture is high, the sweat cannot evaporate so easily, so people have a heavier cooling of time, resulting in a higher heat index.
People should remember that the feeling that when listening to local weather forecasts feel like the temperature they hear may not be enough to determine how each individual will feel in a certain weather. For example, the measurement of the thermal index is given for shady conditions with apparent wind light. In full sun, the temperature may seem warmer than the thermal index indicates. The same tokempokud someone stands in a protected area that receives full sun in winter, can feel a little warmer than the estimated wind of cold.
It feels like a temperature is particularly important for health reasons. If the heat index is very high, people can be highmelted to increased risk of heat exhaustion and decline. Likewise, extreme wind temperatures can expose people the risk of frostbite and hypothermia. It is therefore important that people pay attention to these number except the actual prognosis temperature for this day.
