- Refer to suggested student activity (Appendix 1) at the end of this module. The first requirement for cloud formation is moisture. This moisture is constantly recycled through the earth-. atmosphere system by means of the hydrologic cycle (figure 1). Moisture in this cycle exists normally in the 3 states of water: solid, liquid, and vapor.

- Clouds can occur at any level of the atmosphere wherever there is sufficient moisture to allow condensation to take place. The layer of the atmosphere where almost all cloud exists is the troposphere, although the tops of some severe thunderstorms occasionally pierce the tropopause.

What are clouds? Clouds will either be composed of ice or water droplets depending on the height of the cloud and the temperature of the atmosphere. Because the droplets are so small, they can remain in liquid form in temperatures as low as -30 °C. Extremely high clouds at temperatures below -30 °C are composed of ice crystals. How do clouds form? Clouds form when the invisible water vapour in the air condenses into visible water droplets or ice crystals. There is water around us all the time in the form of tiny gas particles, also known as water vapour. There are also tiny particles floating around in the air - such as salt and dust - these are called aerosols.

Are Clouds a Gas or a Liquid? Clouds are a combination of water droplets and condensation nuclei. Clouds are formed when evaporation pulls water into the air creating the gaseous form of water called water vapor. When the air becomes saturated, water vapor condenses into liquid water droplets. However, it takes more than gaseous water vapor and liquid water droplets to form a cloud. These water droplets require condensation nuclei to condense upon such as dust, pollen, or smoke. Millions of water droplets collide and gather to form a cloud.

Cloud Formation: A Brief Explanation of How Do Clouds Form For the water vapor to condense at a particular point and form clouds, the moist air that rises above the earth's surface has to undergo a series of processes. Clouds thus, may be formed in five different ways. These include: Formation of clouds can sometimes cause a cloud field.

Previously Asked Questions Humidity is a measure of the amount of water vapor in the air, not the total amount of vapor and liquid. For clouds to form, and rain to start, the air does have to reach 100% relative humidity, but only where the clouds are forming or where the rain is coming from. This normally happens when the air rises and cools.

Cloud physics Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. Clouds consist of microscopic droplets of liquid water (warm clouds), tiny crystals of ice (cold clouds), or both (mixed phase clouds). Cloud droplets initially form by the condensation of water vapor onto condensation nuclei when the supersaturation of air exceeds a critical value according to Köhler theory.

What layer of the atmosphere are the clouds located? The troposphere. The troposphere is one of the four layers of the atmosphere (0-10km in altitude) containing water vapour. Clouds are formed by water condensing and as air cools.This is why cloud formation is possible because the temperature of the troposphere decreases with altitude.he troposphere is one of the four layers of the atmosphere (0-10km in altitude) containing water vapour. Clouds are formed by water condensing and as air cools.

Cloud Development The requirements for sufficient water vapor and CCN are rarely the limiting factors for cloud development. Typically, the limiting factor is a cooling mechanism. Thus, the air temperature needs to be lowered to the dewpoint temperature for a cloud to form. If a cooling mechanism is not present, clouds will not form. Common Cooling Mechanisms: The following are common mechanisms in the atmosphere that cause cooling and, hence, may be associated with cloud formation: 1  Radiative cooling from the ground. 2  Evaporative cooling. 3  Cooling by lifting (as air rises in the troposphere, it cools) 4  Mechanical lifting Lifting near a front. Lifting in low pressure systems.

atmosphere Almost all weather develops in the troposphere because it contains almost all of the atmosphere’s water vapor. Clouds, from low-lying fog to thunderheads to high-altitude cirrus, form in the troposphere. Air masses, areas of high-pressure and low-pressure systems, are moved by winds in the troposphere.

Cumulus Clouds Information 1 These clouds are also known as fair weather clouds at times; courtesy, their ability to act as an evidence to relatively stable air. 2  On an average, these clouds form at an altitude ranging between 8,000 ft. to 20,000 ft., but their formation at a much lower altitude is also quite common.

Weather Atmospheric Conditions. Weather is the state of the atmosphere at a specific time and place, with respect to temperature, precipitation, and other factors such as cloudiness. Weather is generated by many forces, some obvious, some not. Warm, humid air masses blowing in from oceans, for example, fuel rains.

Types of Clouds Put simply, clouds develop out of the process of changing moisture from a gas to liquid. This occurs through a process called convection. As solar radiation heats the ground and the air immediately above it, the warm air becomes lighter and the flow of air carries this warm air upward.

- Clouds formed by vertical currents in unstable air are cumulus meaning accumulation or heap; they are characterized by their lumpy, billowy appearance. Clouds formed by the cooling of a stable layer are stratus meaning stratified or layered; they are characterized by their uniform, sheet-like appearance.

The Science Behind Clouds â On a Cloudy Day You Can See Weather The air expands and cools, and clouds form as the temperature drops below the dew point. In other words, cold air cannot hold as much water vapor as warm air. Invisible particles in the air in the form of pollution, smoke, dust or even tiny particles of dirt help form a nucleus on which the water molecules can attach.

What are clouds? The warmer the air is, the more water vapour it can hold. Clouds are usually produced through condensation-as the air rises, it will cool and reducing the temperature of the air decreases its ability to hold water vapour so that condensation occurs.

How Do Clouds Form? Once water molecules collect they mix with the other atmospheric ingredients to form a cloud. slide 4 of 9. Dust Particles Dust particles are a necessary atmospheric ingredient in cloud formation. Unless relative humidity exceeds 100%, dust particles must be present in order for a cloud to form. This dust can come from a number of sources such as ocean sea spray, volcanoes, fires or cars.

- Atmospheric stability, or more importantly, instability, also plays an important role in thunderstorm development. Rising air is needed to produce clouds, and rapidly rising air is needed to produce thunderstorms.For air to rise rapidly, it must become buoyant compared to the surrounding air.tmospheric stability, or more importantly, instability, also plays an important role in thunderstorm development. Rising air is needed to produce clouds, and rapidly rising air is needed to produce thunderstorms.

Weather - Solar Energy, Humidity, Clouds, And Precipitation, Atmospheric Pressure And Winds, Terrestrial Characteristics conditions air earth meteorology. Weather can be defined as the condition of the atmosphere at any given time and place. Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.

- Cirrus clouds are formed when water vapor undergoes deposition at high altitudes where the atmospheric pressure ranges from 600 mbar at 4,000 m (13,000 ft) above sea level to 200 mbar at 12,000 m (39,000 ft) above sea level. These conditions commonly occur at the leading edge of a warm front.
