This change of temperature rather decrease of temperature pole-ward is called temperature gradient. The rate of decrease of temperature between the tropics of Cancer and Capricorn is rather low and therefore temperature gradient is insignificant but temperature decreases more rapidly from the tropics pole-ward and therefore temperature gradient is also very high.
An air parcel moved upwards will warmer than the surrounding atmosphere, therefore less dense and thus buoyant. The parcel will tend to continue to rise due to buoyancy, The new measurements show that the temperature excess ranges from 30 to 70°C and peaks at an altitude of 100 km. This region of Venus’s atmosphere contains light hazes of various aerosol particles, composed chiefly of sulphuric acid and water. These are highly variable and can often be seen as bright regions of the planet. A temperature gradient is a physical quantity that describes in which direction and at what rate the temperature changes the most rapidly around a particular location. The temperature gradient is a dimensional quantity expressed in units of degrees (on a particular temperature scale) per unit length.

The heat flux and the temperature gradient in the lower atmosphere. November 2004; Geophysical Research Letters 31(22) DOI: 10.1029/2004GL020053. Authors: Chad William Higgins. Oregon State It is suggested that when the temperature anomalies in the lower troposphere are relatively warmer (cooler) than in the upper troposphere, the atmosphere is less (more) stable and favors an El Niño (a La Niña) event to develop. ENSO evolutions in 1997–1998 and 2014–2015 events are good examples of this relationship.
Temperature gradients in the atmosphere are important in the atmospheric sciences.
On average, water vapor accounts for 0.25% of the mass of the atmosphere. At an altitude of about 10 km, a region of weak vertical temperature gradients,
However, this normal lapse rate varies with height, season, latitude and other factors. Indeed the actual lapse rate of temperature does not always show a decrease with altitude.
Of course, we know that the atmosphere is not isothermal. In fact, air temperature falls quite noticeably with increasing altitude. In ski resorts, you are told to expect the temperature to drop by about 1 degree per 100 meters you go upwards. Many people cannot understand why the atmosphere gets colder the higher up you go.

METEO 300. Fundamentals of Atmospheric Science First we have to specify where we want to measure the temperature gradient. Then we simply need to
Il s'exprime généralement en °C/100m (variation de température en degrés Celsius par 100 mètres de gain d'altitude).
The temperature gradient of about -1 K/ (100m) applies strictly speaking only to dry air that contains not gaseous water. This is why this temperature gradient is also called the dry adiabatic lapse rate. However, air always contains a certain amount of moisture, i.e. there is gaseous water in the air (called water vapor).
The temperature gradient shown here is crucial for the temperature at the surface. + – + – + – +. There is no ”Greenhouse Effect”.
1) What is Conduction - Therma When it reaches the higher altitude, it experiences the lesser atmospheric pressure which allows the hot air to easily expand and cool. Due to this reason, the temperature keeps on decreasing while It would be perfectly feasible to define the average temperature of a layer in the atmosphere by calculating its mean value in degrees C (or Kelvin) between two vertical points, but an easier, practical way to measure this same mean temperature between two levels can be gained by subtracting the lower height value of the appropriate isobaric surface from the upper.
