"Cloud Observation" Weather PPT Download

Part One: Observing Clouds

1. What is cloud?

Clouds are visible aggregates composed of thousands of small water droplets or ice crystals suspended in the atmosphere.

2. What is the significance of cloud observation?

The formation, appearance characteristics, amount, distribution and evolution of clouds not only reflect the movement, stability and water vapor conditions of the atmosphere at that time, but are also one of the important signs that predict future weather changes.

In the weather calendar we have used the terms sunny, cloudy, overcast, etc. to describe and record observations of cloud cover. So, how are these different weather conditions divided?

Cloud Observation PPT, Part 2: Classifying Clouds

How do meteorologists classify clouds?

Meteorologists divide clouds into three categories based on their height and shape: cumulus, stratus and cirrus.

What are cumulus clouds?

cumulus

Clouds that are higher than stratus clouds and look like cotton piles are called cumulus clouds. Cumulus clouds are usually associated with sunny weather, but they can also develop into cumulonimbus clouds and form thundershowers.

stratus

Flat, layered clouds that form close to the Earth's surface are stratus clouds. Usually gray. Sometimes it covers most or even the entire sky. If stratus clouds thicken, drizzle, heavy rain, or snow will occur, also known as nimbostratus.

cirrus

Thin, feathery clouds are cirrus clouds. Cirrus clouds can only form at high altitudes where temperatures are very low, so cirrus clouds are composed of tiny ice crystals.
