1. On Figure 8-2, consider a sample of air denoted by the * with a tem- perature of −15◦C and ea = 1.72mb. If, at −15◦C, es = 1.91mb with respect to water, what is the RH?
2. What will likely happen to liquid water when the surrounding envi- ronment is unsaturated?
3. What is the RH with respect to ice if, at −15◦C, es = 1.65mb with respect to ice?

Risk of flooding

The River Mole in Surrey has burst its banks in several areas and an Environment Agency severe flood warning - which means a danger to life - has been issued for Leatherhead.

§  Some 150 properties have been flooded in England, mainly in Surrey and Kent, with numbers expected to rise - the EA has said.

§  In Surrey residents were evacuated from their homes in Dorking, Leatherhead and Guildford, while more evacuations occurred in Tonbridge, Kent.

§  On the roads, many major routes were flooded or blocked in Kent, Hampshire, Surrey, Sussex and Cornwall.

§  Tim Field from the Energy Networks Association said engineers were working to restore power to some 50,000 people still cut off in the east and south-east of England.

§  Southern Electric said some 19,500 customers, most in south Hampshire, Surrey Bernal sent this picture of the roads around Dorking, in Surrey

Winds are expected to ease today, before heavy rain and gales pick up again on Friday.
