Atmosphere/ Jetstream

Discover the diverse layers of Earth's atmosphere, from the Exosphere to the Troposphere. Learn about key characteristics, such as temperature variations, air molecule density, and the role of the Jet Stream in shaping weather patterns. Unravel the mysteries of the Ozone layer, auroras in the Mesosphere, and the dynamic nature of the Thermosphere. Let's delve into the atmospheric wonders that surround our planet.

Presentation Transcript

  1. Atmosphere/ Jetstream

  2. Exosphere- 500 km and beyond • Outermost layer • Very few air molecules • No clear boundary between this layer and space

  3. Thermosphere - 95km to 500 km • Warmest layer of the atmosphere • Reflects radio waves • Lower layer is called the ionosphere, this is where auroras take place.

  4. Mesosphere – 45 km to 95km • Coldest part of the atmosphere

  5. Stratosphere – 10km to 45 km • Ozone layer located here • Little to no water vapor • Tropopause- (between strato and tropo) Jet stream is located here

  6. Troposphere – ground to 10km • Closest to the ground • 99% of all weather takes place here.

  7. Jet Stream

  8. A wind current, which moves around Earth capturing and changing anything in its path. • If forms high in the tropopause, between two air masses of very different temperatures. • The greater the temp difference, the faster the wind blows in the jet stream. • This “river” of air can reach speeds up to 643.7 km/hr and be several hundred miles wide. • Usually form in the winter when there is a greater contrast in temp of cold air masses and warm air masses • Jet stream does NOT cause weather conditions, but exists because of certain weather conditions.
