Well I went flying today to take advantage of the weather. Today saw a sea breeze front push in over Caboolture producing frontal lift on the western side.

I took some photos to show those of us that have not yet flown a sea breeze front. The cool moist ocean air is drawn in by inland convection from the coast and is forced up when it collides with the established inland air mass. As it rises it condenses and forms cloud usually ragged and substantially lower than the established inland cloud base.

The inland air is also being forced up by the sea breeze pushing in under it. This is where the nice lift is, on the inland side of the lower frontal cloud.

I hope you can see this in the photos. It is not usually a nice straight continuous line but broken into slabs along a line up the coast. Today's front was broken like this. At one stage I flew west from the front to take a photo looking back from a distance so you could clearly see the two different cloud bases.

I hope these photos help you to recognise the next front.

Cheers,

Speedy
