How Changing Weather Conditions Make Contrails Show Up

On a recent walk in the hills my day started like thisDSC_0717.JPG

The relative humidity chart from InstantWeatherMaps.com shows around 50% RH at 300mb. The red dot is my approximate location.

By the end of my walk the skies looked like this

The relative humidity chart from InstantWeatherMaps.com shows greater than 90% RH at 300mb.

But to my frustration SQ297 seem not to follow the same flight path each day and can travel over head 1000 clicks north of me or as today just beyond my sight yet for a few days over 2 weeks it went right over head

It is a false colour plot of backscatter (colour scale) against time (X axis) and vertical range ( Y axis) as clouds/aerosols/contrails etc. advect (with the wind) over a Met Office lidar ( in this case for Eskdalemuir). The cloud base is marked in black and the colour is an indication of the amount of backscatter in (relatively) arbitary units, as in the case of these lidars, which operate in the IR, there is virtually no air backscatter to use as a reference value. The light blue, in this case, near the ground is aerosol backscatter in the boundary layer, and the rest is cloud/contrails of various sorts. The black dots higher up are probably contrails which pass through the laser beam in a relatively short time. I should add that the signal to noise decreases with height as 1/(range squared), so it runs out of steam higher up, although it can still see the denser clouds (but not aerosols).
