0.0 - Complete Beginner: This level includes very basic vocabulary and simple phrases, accompanied by clear visuals and context, making it suitable for individuals with no prior knowledge of the target language. 
0.3 - Beginner: This level features simple sentences and commonly used vocabulary. The video may provide some visual aids and context to help with understanding. 
0.5 - Intermediate: This level presents more complex sentences and a broader vocabulary range. It may include some idiomatic expressions that require additional background knowledge. 
0.6 - Upper Intermediate: This level includes specialized vocabulary and concepts relevant to specific fields. Viewers should have a reasonable proficiency in the target language for full understanding. 
0.8 - Advanced: This level uses advanced vocabulary and intricate sentence structures, potentially involving nuanced discussions that necessitate a strong command of the language. 
1 - Very Advanced: This level is aimed at fluent speakers, incorporating specialized terminology and concepts that may not be familiar to all native speakers.
 Title: Kial la vento blovas?
Description: Ĉu ĝi estas bonvena venteto en varma tago, ĉu detrua skualo dum ŝtormo, vento ĉiam komenciĝas sammaniere: kun diferencoj en aerpremo.

Caption: Why does the wind blow?
Wind is a part of weather that we’ve all experienced at one time or another.
And whether it’s a welcome breeze on a hot day, or a destructive gust during a storm,
it all starts in the same way: differences in air pressure.
Air is a mixture of gases in Earth’s atmosphere.
The weight of these gases pushes down on Earth, creating air pressure.
How does air pressure cause wind?
Wind is caused by differences in air pressure, and temperature can affect these differences.
Gases are made up of tiny particles called molecules.
When gas molecules in our atmosphere are warmed by the Sun,
they do three things: The molecules move quickly
They spread out
And they rise up.
As warm air rises up into the atmosphere, it isn’t pushing down on Earth quite as much.
This creates an area of low air pressure.
When gas molecules are cold, they do the opposite:
They slow down,
Move closer together,
And sink.
As cold air sinks down in the atmosphere, the weight of the air
pushes down on Earth’s surface a bit harder.
This creates an area of high air pressure.
The Sun doesn’t heat all of Earth equally, so there are high pressure areas and low pressure areas
all over the planet.
In general, air always flows from an area of high pressure to low pressure.
So, cool air in high pressure areas will rush into the low pressure area created by rising
warm air.
This rushing air is called wind.
Why is some wind a gentle breeze while other wind is a strong gust?
The strength of the wind depends on the temperature and pressure difference between the warm and
cool air.
Wind is important because it moves more than just leaves and trees – it moves storms, too.
Meteorologists can study wind direction to help figure out where a storm is moving next.
They can also use weather satellites, to track wind by the movement of clouds.
This helps to forecast the path of big storms, such as hurricanes.
Whether it’s a major storm like a hurricane or a gentle breeze on a hot day, all winds
form in the same way – and now you know why!
