Someone at the BBC needs to learn about temperature conversion

http://news.bbc.co.uk/1/hi/england/dorset/7974891.stm
Whether you believe in Global Warming or not the only thing which will drop the rainfall in summer is a decent high pressure area over the UK which is largely controlled by the jet stream

Re: Someone at the BBC needs to learn about temperature conversion

well whats the coldest -40 C  or -40F
also +4C does equal 39.2F  but a rise of 4C = a rise of 7.2F, just looked at the original report and no mention of temps in there, but dont worry Jim it wont reach that temp until another 71years

sooner they get rid of the confusing & plain wrong ( regarding where 0o is ) Fahrenheit scale the better -- never understood it - never had to -- always used Kelvin & degrees Celsius

Extract from the executive summary of the report
Quote
Likely impacts of climate change on the Dorset Downs and Cranborne Chase
Evidence from the UK Climate Impacts Programme (2002) shows that the climate in the Dorset Downs and Cranborne Chase over the coming century is likely to become warmer and wetter in winter, and hotter and drier in summer. In addition, rainfall intensity will probably increase. Extreme events such as heat waves and storms are predicted to increase in frequency and severity.
By 2080, if we do not reduce greenhouse gas emissions, the climate of the area may resemble that of Portugal. The mean temperature in January could increase by 3°C and in July by 6°C, while average rainfall may decline by 12%. Portugal has arid chalk landscapes where the impact of drought, floods, and soil erosion are already being felt, and some parts of the country experience water shortages every other year..

If you want to make your own thermometers it's easier to do it to the Fahrenheit scale than Kelvin or Celsius. The former scale used 3 points, which are:
Quote
According to Fahrenheit himself in a journal article he wrote in 1724,[2] his scale is based on three reference points of temperature. The zero point is determined by placing the thermometer in a mixture of ice, water, and ammonium chloride, a salt. This is a type of frigorific mixture. The mixture automatically stabilizes its temperature at 0 °F. He then put a thermometer into the mixture and let the liquid in the thermometer descend to its lowest point. The second point is the 32 degree found by putting the thermometer in still water as ice is just forming on the surface.[3] The third point, the 96 degree, was the level of the liquid in the thermometer when held in the mouth or under the armpit. Fahrenheit noted that, using this scale, mercury boils at around 600 degrees.

Re: Someone at the BBC needs to learn about temperature conversion

If Mr Fahrenheit puts his thermometer in "still water" when ice is forming on the surface, the temperature of the water must be higher than 32 degrees - or it would be ice.  Cheesy
The zero point was meant to be the coldest possible temperature (so you would never need negative degrees). But he was wrong.

Re: Someone at the BBC needs to learn about temperature conversion

If you had a pond with still and pure water with ice on the top what will the temperature be at 6cm and 30cm below the ice?

not been called a youngster for a while - if I wore a toupee I might look like one though  Wink
cwt is a hundredweight - hundred whats - have nae clue
LSD is a limited slip differential
not going to try and learn a 3rd temperature scale
coldest temperature I know of is zero kelvin  = -273.150C

It's currently -273.15 but this is the 3rd value Kelvin zero been given so what will it be in 50 years time? Also there's a 4th temperature scale called Rankine.

yep, had forgotten about rankine - another one that uses tiny units to make temperatures seem 'impressive'

give you a clue on hundredweights there are 112 of them

It depends on the temperature outside Smiley and how deep your pond is.
Note that the maximum density of water is about 4 degrees Celsius.
So it should be warmest near the bottom.

Re: Someone at the BBC needs to learn about temperature conversion

yes - we should have ditched Fahrenheit 30 years ago - along with all other imperial measurements, like the vast majority of the world  Wink
