Water vapor condenses to form clouds when it reaches its dew point, which is the temperature at which air becomes saturated with water vapor. The water vapor then forms tiny water droplets or ice crystals, which come together to create clouds.
Clouds form when air containing water vapor is cooled to its dew point, which is the temperature at which the air becomes saturated with moisture and condensation occurs. This typically happens when warm, moist air rises and cools as it encounters lower temperatures at higher altitudes.
Clouds begin to form at the lifting condensation level (LCL), which is the altitude where air becomes saturated and condensation occurs. If the dew-point temperature is 11 degrees C, the LCL can be determined using the temperature lapse rate and the environmental temperature. Generally, the LCL can be approximated by the formula: LCL (in meters) = (T - Td) × 125, where T is the air temperature and Td is the dew point. Therefore, to find the elevation at which clouds would begin to form, the specific air temperature would need to be known alongside the dew point.
The temperature of the gas in dark dust clouds is typically very low, around 10-20 Kelvin. This low temperature is important for molecule formation because it allows atoms to move slowly and come together to form molecules through chemical reactions. In higher temperature environments, atoms move too quickly to successfully bond and form molecules.
Evaporated water condenses in the atmosphere to form clouds.

Descending air not allow clouds to form because air rises at low pressures.
High Pressure comes down and the clouds are up.
Descending air not allow clouds to form because air rises at low pressures.
Antarctica in August is possibly the most interesting time of year, at least visually. The sun rises for the first time in months, and the hole in the Ozone layer is beginning to form. The earth's most exotic clouds, Nacreous clouds, can be seen. (And they are only visible over Antarctica.) Read more about these clouds, below.
Clouds can form from sea water evaporation during night or day. Basically it depends on wind strength and air temperature.
Cirrus clouds are high enough to be at a low enough temperature for the water droplets to form into ice crystals. However, Cirrus clouds are not precipitation clouds, so no snow or rain can fall from them. The clouds that can cause snow to fall in the right conditions are Nimbostratus and Cumulonimbus clouds.
saturation point and condenses into tiny water droplets or ice crystals, which gather together to form visible clouds. The conditions necessary for cloud formation include cooling of the air, the presence of condensation nuclei, and rising air currents that allow the vapor to reach the saturation point.
The ozone hole forms over Antarctica. It is because of low temperature.
Drops of condensed water in the atmosphere can form clouds, fog, or precipitation such as rain or drizzle, depending on atmospheric conditions like temperature, pressure, and humidity.
The base altitude at which clouds form can be determined using the dew point temperature and the environmental lapse rate. By measuring the temperature and humidity at ground level, you can calculate the lifting condensation level (LCL) using the formula: LCL (in meters) = (temperature - dew point) × 125. Additionally, weather balloons or radiosonde data can provide vertical profiles of temperature and humidity, helping to pinpoint the altitude where air cools to its dew point and clouds begin to form.
Clouds form high in the air because that is where the temperature and pressure conditions are right for water vapor to condense into liquid water or ice crystals. The air needs to cool and reach its saturation point for clouds to form, which typically occurs at higher altitudes where the temperature is colder. Additionally, this altitude range allows for the vertical development and movement of clouds in the atmosphere.
