I want to make a pressure analysis of wind on my curved roof.

What I am confused of are the values of the pressure, which I get from the Solid works analysis. Take a look:

The maximum value I got is 101348 Pa and minimum one 101290 Pa.

I know that normal atmosferic pressure at sea level is 101325 Pa.

So by knowing this, how can I get my wind pressure load on the surface?

I know 1000 Pa = 1 kN/m2, so by that I can get a uniform load from the wind pressure. Fore example 101348 Pa = 101,348 kN/m2. But this is too high, and not the way to do it right?

Any help please?

Thanks.
