High humidity and low temperature, high temperature and low humidity.

Humidity is the water content in the air.

Temperature:

Temperature is a physical quantity that indicates the degree of heat and cold of an object, and it is the intensity of molecular thermal motion of the object at the microscopic level. According to an observable phenomenon (such as the expansion of mercury column), the degree of heat and cold is measured by one of several arbitrary scales. Temperature can only be measured indirectly through some characteristics of an object that changes with temperature. The scale used to measure the temperature value of an object is called a temperature scale. It specifies the reading starting point (zero point) of temperature and the basic unit for measuring temperature. The international unit is the thermodynamic temperature scale (K). At present, other temperature scales widely used in the world are Fahrenheit scale (F), centigrade scale scale (C) and international practical temperature scale. From the point of view of molecular motion theory, temperature is a sign of the average kinetic energy of an object's molecular motion. Temperature is the collective expression of a large number of molecular thermal movements, which has statistical significance.

Humidity:

Humidity, a physical quantity indicating the dryness of the atmosphere. At a certain temperature, the less water vapor in a certain volume of air, the drier the air; The more water vapor, the wetter the air. The degree of dryness and wetness of air is called "humidity". In this sense, commonly used? Absolute humidity, relative humidity, relative humidity? Mixing ratio, saturation deficit and dew point; If the weight of steam in wet steam accounts for the percentage of the total weight (volume) of steam, it is called the humidity of steam. The comfortable humidity of human body is: the relative humidity is lower than 70%.
