How do clouds form and produce precipitation?

How do clouds form and produce precipitation?

Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. These particles, called “condensation nuclei,” provide a surface for water vapor to condense upon. This helps water droplets gather together and become large enough to fall to the Earth.

Why do clouds and precipitation form near fronts?

Cold air is more dense than warm air, so when a warm air mass meets a cold air mass, the cold air ends up below the warm air. Once the air has risen, it cools and clouds can form. Weather fronts can cause clouds to form.

What clouds produce precipitation?

Nimbostratus clouds bring continuous precipitation that can last for many hours. These low-level clouds are full of moisture. Cumulonimbus clouds are also called thunderheads. Thunderheads produce rain, thunder, and lightning.

Why do some clouds produce rain and others don t?

The droplets of water in a cloud have weight, so gravity gradually polls them down and they sink lower and lower. As most of them fall, they reach a warmer layer of air, and this warmer air causes them to evaporate.So here we have clouds that don’t produce rain. Naturally, the droplets won’t evaporate.

Do all clouds cause rain?

We know that not all clouds produce rain that strikes the ground. Some may produce rain or snow that evaporates before reaching the ground, and most clouds produce no precipitation at all. When rain falls, we know from measurements that the drops are larger than one millimeter.

What are the two ways that fog forms?

The two common types are steam fog and frontal fog. Steam fog forms when cold air moves over warm water. When the cool air mixes with the warm moist air over the water, the moist air cools until its humidity reaches 100% and fog forms.

What does fog stand for in construction?

FOG – Fat Oil and Grease.

How do you fog?

Advection fog forms when warm, moist air passes over a cool surface. This process is called advection, a scientific name describing the movement of fluid. In the atmosphere, the fluid is wind. When the moist, warm air makes contact with the cooler surface air, water vapor condenses to create fog.

What causes fats oils and grease?

Fats, oils, and grease (FOG) comes from meat fats in food scraps, cooking oil, shortening, lard, butter and margarine, gravy, and food products such as mayonnaise, salad dressings, and sour cream. FOG poured down kitchen drains accumulates inside sewer pipes.

What is fats oils and grease?

Fats, Oils, and Grease (FOG) – Fats, Oils, and Grease (FOG) are a byproduct of food preparation, cooking, and cleanup of dishes, pots and pans, utensils, moping of grease laden floors, etc. Fats, oils, and grease (FOG) compounds consist of fatty acids and glycerol.

How can fog cause problems?

Clear skies also help any warm temperatures from staying at the surface. This means the temperature will cool faster and reach the same value as the dew point quicker. Fog can cause visibility issues on the road, preventing you from seeing cars or other landmarks right in front of you.

What causes river fog?

The cold lows and fog are both outcomes of cold air drainage. During the day, the sun heats the air just above the surface all day long. The air near the surface becomes so cool on clear nights that it condenses into a cloud that we know as fog, mainly sticking to the low-lying areas and river valleys.
