I think it's sewer gas. A kind of food processing :-) On high pressure days, the outside air flows into the relatively low pressure of the sewers, and you smell nothing. On low pressure days, the relatively high air pressure inside the sewers must now equalize, so it blows out....usually in a low/easiest access point.
I'm not sure about all manholes, but many low sewers (especially around the river) stink when there is a sudden drop in air pressure from a weather front.
