What determines the feels like temperature (with pictures) o goshi technique

Often, simply learning the expected high and low temperatures isn’t adequate preparation for going outdoors. Many people wait to hear the feels like temperature before they plan what to wear and where to go on any given day. This temperature gives people an idea about how they will feel outdoors, rather than a simple temperature that leaves them guessing. To determine this temperature, meteorologists must take into account factors like the wind chill and the heat index.

The feels like temperature is often determined in part by the wind chill during the winter months. Wind chill involves measuring the temperature as it is felt on the skin, which is determined by the air temperature and wind speed. In other words, it’s a measure of the heat skin loses when the wind blows on it. The wind chill is typically always lower than the temperature of the air because wind increases how quickly moisture evaporates from the skin and serves to move heat away from the body. At higher temperatures, wind chill is considered far less significant and is usually not reported.

The heat index takes into account both the air temperature and the humidity in determining how warm temperatures feel to a person outdoors. When an individual perspires, the water in his or her sweat evaporates. This helps cool the body because heat is carried away during evaporation. When humidity is high, sweat cannot evaporate as easily, so people have a harder time cooling off, resulting in a higher heat index.

People should keep in mind that the feels like temperature they hear when listening to a local weather forecast may not be enough to determine how each individual will feel in certain weather. For example, heat index measurements are given for shady conditions with light wind evident. In full sunshine, the temperature may seem hotter than the heat index indicates. By the same token, if someone is standing in a sheltered area that receives full sun in winter, he or she may feel a bit warmer than the estimated wind chill.

The feels like temperature is particularly important for health reasons. When the heat index is very high, people may be at increased risk for heat exhaustion and heat stroke. Likewise, extreme wind chill temperatures can put people at risk for frostbite and hypothermia. As such, it is important for people to pay attention to these numbers in addition to the actual forecast temperature for the day.

sweat will continue to cling to your clothes until you’re literally drenched, but the sweat doesn’t evaporate; it just keeps adding to the already existing sweat. It’s brutal, deceptively brutal in Miami. If you want to test this come to central or south Florida in the middle of summer — either Orlando, Florida, Tampa, Florida or Miami, Florida in July will suffice — try any of the above destinations in July. So despite all warnings not to, you schedule a vacation for Florida in July or August for two weeks and that’s all it will take — you’ll never come back to the state of Florida in the middle of summer ever again.

So, 90F in Phoenix, Arizona with 10 percent humidity means it’s dry — 90F with 10 percent humidity actually feels like 85F and dry. You sweat, it evaporates, no sweat actually sticks to your clothes and it’s more like a warm oven when you step outdoors, but it’s not that bad.

This is not to say that high temperatures in extremely dry climates are not as severe. Actually, with Las Vegas, Nevada or Death Valley, California, as examples, a dry 110F with 10 percent humidity equals 104F. There’s no humidity to inflate the "feels like temperature" and actually the low humidity drops the heat index or real feel to 104F. 110F, even with the noted heat index of 104F at 10 percent humidity, is still a very high temperature that will kill you. That’s how Death Valley got its name. You’ll dehydrate in 110F easily, but it’ll only feel like 104F. I know, big difference, right? You just won’t feel the sweat sticking to you in the desert because as fast as you sweat, the sweat evaporates just as quickly and you stay dry.

With hot, humid subtropical/tropical climates, high humidity is a factor due to proximity to water and high humidity works almost as a multiplier with the temperature to create a higher heat index or a higher real feel temp than the actual air temperature. Without any wind, the humidity lingers — step off a plane in Miami, Florida in the spring or summer departing from Chicago, Illinois and Miami will greet you with a punch in the face. Not literal, but you’re going to feel the heat and humidity in Miami because it’s like a strong wall of air that hits you immediately and it almost suffocates. The same goes for any state in the southeast close to the Gulf of Mexico in summer. Summers in the Southeast are unkind and it’s the high humidity that accentuates that miserable unpleasantness.

In places like Hawaii or Guam – islands — with a gentle wind or trade winds, the humidity will be high, but at least on windy days, the winds help to offset the humidity or move the air around so that the sweat doesn’t stick to you as much. With no wind, Hawaii and Guam will have that high heat, high humidity factor and the sweat will stick to you and then it’s not comfortable.

Because I brought up Thailand, the current temperature in late March in Bangkok, Thailand at 5 a.m. is 84F, with humidity = 84 percent, and a heat index = 96F. If the forecast calls for a clear, sunny day with a high temperature of 96F, humidity = 45 percent, it will feel like 106F for the heat index.
