### Sea-breeze phenomenon explanation

This time I will tell you about the sea-breeze phenomenon explanation.

I think this phenomenon is of interest for you too.

The sea-breeze phenomenon is a widely known and long ago explained phenomenon, but how differently it is explained...

What is used to be said about the sea-breeze phenomenon that it happens on the seaside shores or on the large lakes at summer time.

And it is true.

What else is said is that in summer, during the day, the land is warmed more than the sea water.

And it is true too.

What is said next - is different.

It is said, the warm land warms by convection the air above it, the warmer air rises and the cooler air comes on shore from the sea...

Everyone knows that, it is taught in schools for centuries now. The school teachers taught us that. They know it from their teachers. But it does not happen that way.

So, what exactly, in my humble opinion, I realized happens here.

Sea-breeze phenomenon happens in summer, not in winter. In winter land also gets warmed at much higher temperatures than sea waters do. But in winter we do not witness any sea-breeze phenomenon.

Why, doesn't the convection work at winters, at least a little bit?

No, there is not any sea-breeze in winter.

And here it is what exactly happens:

We know that lands specific heat cp = 0,19 cal/gr.oC

and water's specific heat cp = 1 cal/gr.oC

- so it is 5 times less on the land. Let's say land gets warmed from 20 oC to 60 oC and sea gets warmed from 20 oC to 28 oC which it is 5 times less.

What is next - next is the Stefan-Boltzmann law application.

Land would have T.land = 273 + 60 = 333 K

Sea would have T.sea = 273 + 28 = 301 K

J.land.emit = σ*333⁴ = σ*12.300.000.000

J.sea.emit = σ*301⁴ = σ*8.200.000.000

σ - is the Stefan-Boltzmann constant

We see here land emits 12,3 /8,2 = 1,5 times stronger intensity IR radiation. In winter the difference is even bigger...

But in winter there is a very small amount of water vapor (the major IR radiation absorbing factor in the Earth's atmosphere) in the air.

So when irradiated stronger, in the summer, the water vapor absorbs more energy above the land than above the sea in all the air's volume 1,5 times more...

The air above land gets expanded 1,5 times more than above sea...

This expansion difference makes the air above land to become lighter, and it makes the air above sea to enter the shore and the sea-breeze phenomenon to begin.

What else is needed to say - the air cannot be warmed by the hot land surface by contact, the air is the perfect insulator, everyone knows that.

So how on earth, a perfect insulator can be warmed in its entire volume to create a sea-breeze phenomenon?

Only by absorbing more IR radiative energy, because of the summer time much larger amount of moisture being present in the entire air's volume.

Of course this paradigm doesn't correspond to the thought that in summer time all the IR radiation being absorbed by the air's water vapor content.

The water vapor content in the air is about 3 % by volume at most. It cannot absorb all the outgoing IR radiation.

What we see here is that above the land the iR radiation is 1,5 times stronger, and we conclude that it is absorbed there 1,5 times stronger.

And what all this has to do with our topic?

I think it is a good demonstration what IR radiation differences between land masses and sea waters can accomplish.

It is a very good argument in favor of the Reversed Milankovitch cycle too.

Interesting:

cp.water /cp.land = 5

5¹∕ ⁴ = 1,495 = 1,5

and 1,5 times stronger the IR radiation is from land than from sea waters...

Notice:

We have observed the chimney, or the bone-fire smoke rising upwards.

But here we have the already hot gases produced by the fire rising and creating the convection process.

Also we have observed the slope gliding.

The air is getting warmed at higher level on the mountain slopes which are oriented towards South.

The mountain slopes are getting warmed much more than the surrounded the mountain plains, because the slopes' surface angle is closer to the perpendicular towards the rays of sun.

Consequently, the air above the slope is IR irradiated with a higher intensity, than that above the plain.
