Define the atmosphere

a layer of gases up to 40-kilometer altitude that is kept to the Earth due to the gravity force

10

What is the atmosphere made up of?

nitrogen (78%), oxygen (21%) and other 1% of so called trace gases (argon, helium, water vapor, carbon dioxide…)

10

What is the stratification of atmosphere based on?

Changes in temperature

10

What is ISA?

It is an atmospheric model of how different properties of the Earth's atmosphere change over a range of altitudes

10

Why has ISA been established? (2)

to provide a common reference for standardization of aircraft performance (assessment, comparison) and is used by pilots to calibrate the flight instruments

10

Name three characteristic features of troposphere.

laps rate - 6.5 0C/ 1000m; The thickness: 8km-16km; temperature: -50 to -80; All weather phenomena takes place there;

10

What are tropopause folds?

places where cool air meets hot air 40o, 55o, 60-700

10

Where can the protective ozon layer be found? What does it protect us against?

In stratosphere; against harmful sun radiation

10

Explain the greenhouse effect.

heat is trapped in the atmosphere by greenhouse gases.

10

What is the amount of water vapor in the air?

humidity

10

Define surface wind currents.

Steady large- scale winds that blow in a particular area/ in given latitudes caused by changes in temperature and Coriolis effect

10

Name three surface wind currents.

doldrums, trade winds, westerlies, polar easterlies

10

Define "precipitation"

rain, snow, sleet, or hail that falls to the ground

10

Explain how a microburst is formed.

a shaft of fast-moving cold air that hits the earth from high up in the atmosphere, then explodes upwards and outwards.

10

Explain what sleet is.

A mixture of rain and snow

10

Explain what drizzle is.

Very light rain
