thermal

1. of, relating to, caused by, or generating heat or increased temperature
2. (of garments or fabrics) specially designed so as to have exceptional heat-retaining properties
3. Meteorol a column of rising air caused by local unequal heating of the land surface, and used by gliders and birds to gain height

thermal

[′thər·məl]
(meteorology)
A relatively small-scale, rising current of air produced when the atmosphere is heated enough locally by the earth's surface to produce absolute instability in its lower layers.
(thermodynamics)
Of or concerning heat.

thermal

A column of rising air heated by the sun or other phenomena. Sailplane and glider pilots use it for soaring. The pilots recognize the presence of a thermal with the help of a variometer—an instrument having two tubes with red and green indicators. A red means a downward air current, and a green means an upward air current, or a thermal. See variometer.

To simulate the effect of the current and also other planting designs in the park on winter thermal sensation on January 10, 2016, seven different scenarios was simulated:
Human thermal sensation and comfort in transient and nonuniform thermal environments.
PMV index represents thermal sensation of most people for the same the indoor environment, which is related to seven factors including air temperature, air humidity, air velocity, clothing thermal resistance, human metabolism, the type of work that people are engaged in, and mean radiation temperature.
In order to predict the thermal sensation votes for the human body, multiple linear regression analysis was performed with air temperature [T.sub.a] and air velocity, which are components of ETFe TV[F.sub.hta], long-wave thermal radiation [ERF.sub.htaL], heat conduction [ECF.sub.hta], humidity [EHF.sub.ETFe], and short-wave solar radiation [ERF.sub.htaS] as explanatory variables.
Although previous studies have widely researched thermal comfort and IAQ for building indoor environments, there is little quantitative information available on the relationship between acceptable thermal sensation and IAQ, especially for occupants of a health care facility.
To overcome this problem, the thermal sensation index should be calculated as an implicit result of the six previously mentioned variables influencing human's thermal sensation.
There are a good correlation between mean skin temperature and the thermal sensation and thermal comfort of a human body.

PMV (Predicted Mean Vote) index indicates the mean response of a large group of people according to the thermal sensation scale (+3--hot, +2--warm, +1--slightly warm, 0--neutral, -1--slightly cool, -2--cool, -3--cold).
In addition, some patients reported a misinterpretation of sensation (cold for warm or vice versa) or an undefined rather than thermal sensation. Thermal allodynia, a painful sensation to hot and/or cold stimuli well below the control group's pain threshold, was also observed in 12 patients (8 with complete and 4 with incomplete SCI).
