- Is the our weather getting worse
- looking at the case study of the 2012 in the uk where there was a large variety of extreme weather events
- flooding
- severe flash floods
- small village of Hebden in Yorkshire
- Hebden Bridge floods once every five years
- in 2012 it flooded badly on the 24th june, 6th july and 10h july
- 500 businesses and homes were damaged
- flood recurrence interval (estimate of the likeliness that a flood will return )
- in 2012 it flooded badly on the 24th june, 6th july and 10h july
- Hebden Bridge floods once every five years
- small village of Hebden in Yorkshire
- April was the wettest April of the century
- causes of Hebden
- ground became heavily saturated so surface run off wasn't intercepted
- building on flood plains increased the flood risk
- flood plains attract people because they're on flat land and near infrastructure
- people like living near canals due to their beauty
- urbanisation eg paving in gardens reduced interception
- climate change
- climate change
- increase in temperatures leads to an increase in air rising and forming rain clouds
- severe flash floods
- increase in temperature
- Dr simon Boxall from Southampton university investigates weather wierding and he concludes that the last 8 years have been the warmest on record
- met office has been recording weather data using super computers
- great britains Weather has increased by 1°C
- more temperature means more moisture leading to extreme weather events such as hurricanes
- since 1970's the amount of moisture In the earth's atmosphere has increased by 4%
- lead to more tornadoes
- Birmingham tornado 2005, caused £10 million pounds worth of damage per minute
- lead to more tornadoes
- since 1970's the amount of moisture In the earth's atmosphere has increased by 4%
- more temperature means more moisture leading to extreme weather events such as hurricanes
- great britains Weather has increased by 1°C
- 2003 3000 people were killed
- predicted that 11,000 people could be killed by 2080
- climate change due to an increase of co2 in the atmosphere, enhanced green house effect
- our weather isnt becoming worse
- Hebden isn't an appropriate example
- the flood recurrence interval was increased due to
- saturated soils
- village built on a flood plain
- surrounded by a steep hill valey
- increase of urbanisation
- these increased the flood and made them more frequent
- the flood recurrence interval was increased due to
- British are fascinated by our weather
- Media gives the public what they want so we are bombarded with weather news
- This can create the idea that our weather is becoming more frequent but really it is our knowledge of weather that is increasing
- Drama sells news
- more efficient at recording weather
- since 1772 we have been able to record weather
- Met office use super computers to manipulate the weather data and predict future weather
- Hebden isn't an appropriate example
- Jet streams out of line
- 4 bands of air moving at 200 mph
- 2012 spring they moved north bringing dry drought conditions
- in the summer it moved south causing wet cold weather
- weather seemed unusual
- we've seen weather like this before
- in 1031 the church spire of a roof was destroyed and it s thought the cause was a tornado
