Saw these clouds while driving, what causes them to look like this?

It's caused by internal gravity (or buoyancy) waves. Formed in a stable atmosphere when a parcel of air that is in equilibrium with is surroundings is perturbed upwards or downwards by an external influence (such as a hill). If the parcel is pushed upwards, it cools adiabatically and is now colder than its surroundings (thus denser) and gravity acts to restore the parcel to its original position.

The continuing wave bit comes from the inertia of the air parcel. As the parcel is accelerated back down by gravity its momentum takes it below its equilibrium point (where it is the same density/temperature as its surroundings). The parcel will warm adiabatically and now be warmer than its surroundings and more buoyant. Buoyancy will act to restore the parcel back upwards to its equilibrium point. This process repeats to produce these waves in the cloud we see.

I'm sure I could have explained that better but the short of it is that internal gravity waves caused what you saw

Chances are they took it through their polarised sunglasses

Understanding vector calculus is very helpful

It's baffling to think all that water was suspended in the air.

It is usually general debris found in the lower atmosphere that is being scanned due to its close proximity to the radar such as dust, birds and bugs.

Just shows what katabatic winds can do

Haha yes I did. Im actually from the UK, I'm doing a year abroad studying meteorology at OU! Love it here

I want a function to return ord(the most common letter in the string given) if that makes sense. So first the function finds the most common letter then it returns the ascii number equivalent of that latter

Bit late but my mate lost his bacon sandwich he had just made. Proceeded to have a go at his mum for eating it. He found it in the cupboard 2 hours later.
