I read that there is a direct relation between variation of pressure and seismic noise: high pressure correspond to an increase of noise, low pressure correspond to a decrease of noise.
A reasonable answer is in the first page of this paper

Thank you for suggesting an article. Best wishes
I still want to read more in depth about this relationship. Recent work doesn't show any relation between variation of temperature and seismic noise.
Look at this link.

It depends on what you define as seismic noise and which frequency range you refer to. If the range of interest is between 0.5 - 300 seconds, the most comprehensive work was published by Ardhuin et al., 2015 (see enclosed paper). Other frequency ranges have different mechanisms that drive them, such as suggested in the above answers.
Dear Gal,
Firstly, let me thank you for suggested pdf. Secondly, frequency can't be in unit of second but in hz. Period in second. Period of microseisms in the period range 3 to 300 s.
I think its pretty obvious from the units what I mean, and the range of microseisms is definitely extendable to higher frequencies..
but if you want it in Hz... 0.0033-2Hz
