Russian Heat Wave
Impact of Biosphere on a Heat Wave
humans try to cool down cities with man made strutures
will make sure thier food sources dont deplete too fast (ie animals will stat to eat less)
Impact of Lithosphere on a Heat Wave
solar energy
raidates heat
stores carbon
Impact of Hydrosphere on a Heat Wave
contorls the tempture on earth by circulating air
stops forest fires by actng as a barrier
The continuous movement and exchange of water helps to form currents that move warm water from the tropics to the poles (energy education.ca)
Impact of Atmosphere on a Heat Wave
Tries to create precipitation when holding air, to create rain
Tries to regulate pressure
Impact of Hydrosphere on a Heat Wave
acts as a blockade for fire to start from extreme drought
water cycle limits the chance of a heat wave happening
This was a shock to many, as the average summer tempture is normally only 18 degrees celsius. Not to say that temptures don't exceed that, becuase sometimes temptures will climb as high as 30 degrees celsius.
Where and when it happened
In the summer of 2010, Russia experinced record breaking temptures.
Many russian citites were effected. For example, cities such as Yashkul, Belogorsk, Volgograd, Voronezh, Samara, Ryazan and Rostov On Don had temptures reaching as high as 40 degrees celsius.
30 degrees celsius is not even in the same ballpark as 40 degrees celsius is. We saw this as Russian citizens were ill prepared.
What is a heat wave
"a period of more than 5 consecutive days where the daily maximum temperature exceeds the average maximum temperature by 5°C or more". (The World Meteorological Organisation)
Heat waves happen because when pressure is high, the atmosphere moves in and pushes warm air toward the the earths surface.
the air is then futher compressed and heat quickley increses.
Lithosphere After a Heat Wave
soil will crack
soil will dry out
Biosphere After a Heat Wave
Increaesed stress for plants
Reduces plant growth
Effects the food chain
Landscape dies out
Harder to breathe the heavier air (bad for our health)
Mortality
Tree damage, increased leaf fall that then turns into a carbon-sink landscape into a carbon-source
Hydrosphere After a Heat Wave
creates a warmer atmosphere which hold onto water vapor and makes the cycling of water difficult
Could Lead to water shortages
more difficult to carry nutrients
Atmosphere After a Heat Wave
Releases more CO2 into the than is absorbed.
Creates higher temperature in where it should be a cool environment
Increased stress on the Ozone layer
Poor air quality
Before and After
Who, Where and What Were Effected
Animals living in northern Russia
"Species that have adapted to surviving in very specific and limited conditions cannot endure large fluctuations in environmental conditions" (Russia Beyond)
Not enough ice for polar bears and walruses
White sea seals, Arctic Reindeer, and Kamchatka brown bear would all suffer habitat displacement due to the heat.
Why do Heatwaves happen
Heatwaves happen because of solar radation and high pressue.
If there was low pressure, The air would cool as it rises causing it to become more potent with water and become clouds. This is a cause of the water cycle.
High pressure causes the hot air from the atmosphere to be pushed down towrds the earth. This causes surface temptures to rise. Without the air cooling as it rises, The water within the air is unable to become clouds and rain.
