i was alwas under the idea that a seabreeze was called so as the breeze was blowing from the sea, the wind just blows more in cetain directions at different times of the year in different locations

Hey hamburglar,

Being in the ACT, which direction does your seabreeze kick in.

I goooooogled your suggestion, came up with this.

Thanks for educating me.

Can anybody explain why we only get bluebottles on a N.Easter ?

The NE seabreeze (east coast) does all sorts of weird things to the coastal ocean currents. Have you ever noticed the water gets colder on a NE? This is what brings in the blueys!

plus the big air sack acts as a sail

I'll have a stab..



This is a seabreeze system for both Geraldton and Gerroa... Gerroa works off the back of the high, while Geraldton works off the front of a high.. The wind at ground level does not travel along the isobars (in Red), but outwards at an angle (blue).. Then the land heating up in summer does some funky updrafts, and you get cold air coming in from the sea to fill the void.. This is a seabreeze.. It's not just wind from the sea, it's a specific system..

It's the same basic system australia wide, but the eventual direction changes because the land is at a different angle..


-------------------

I heard on Totally Wild that bluebottles travel with their inflated sails, and after a few days of strong NE winds, all the bluebottles on a particular tack will get washed onto the coast.. Other Bluebottles on a different tack sail off in a different direction..

Whats with those crazy blue snail shells you see washed up with the blue bottles...?

Those things are crazy blue

Seabreezes...

Cold sinks, heat rises. It's the concept that makes hot air balloons work, and why your vegies are at the bottom of the fridge. During a summer day, the land is heated by the sun, and this heat is absorbed by the surrounding air. Once this air meets a particular temperature, it begins to rise quite rapidly. As a result, a low pressure area is created at ground level. The sea doesn't heat up as quickly as the land, so the air temperature over the water is much less. As a result, this air is free to move sideways to occupy our new low pressure area. The result is a light to gale force wind which rushes in from the sea to fill the lower pressure area left by the hot air rising from the land. Seabreezes usually happen in spring and summer, when the difference in temperature between land and sea is greatest.

Seabreezes are the most amazing phenonenom. For many years I never really paid much attention to the wind. One day, we arrived (late) at the local river to do some water skiing. It was around 1pm, the water was glassy - perfect conditions. Then, me mate Mick says "Here comes the seabreeze...". Looking across the river we could see an approaching line of rough water. And then it hit us full on - the full glory of a 25 knot seabreeze.

What's even more amazing is that the wind can be travelling faster than the front of the seabreeze. It can be progressing inland at 25 km/h, but the actual wind can be blowing at 35 km/h! Sometimes the seabreeze can reach many kilometers inland, and other days it teases you by staying just offshore, coming in, and then going out again.

So to get a seabreeze, it needs to be hot inland. But too hot and you won't get one at all. To explain why this is the case, we need to understand high's and low's and the squiqqly charts they show on the telly called 'Synoptic Charts'.
