What effect will “the Wells Bowl” and temperature inversion have on dispersal of the emissions?
Responding to comments from the Waste Planning Authority and consultees (including the public) further studies have been completed by independent consultants on the dispersal of emissions. The approved computer model used the local Mendip Weather Eye data for wind direction, and took account of the ground terrain over an area of 10km. Temperature and time of year were also considered to define a “worst case” prediction. The results of this exercise have proved that the location of the site is suitable and, also, that the presence of the Mendips is beneficial to the dispersal effect of the wind. “Temperature inversion” as a concept is irrelevant to the physical (temperature) characteristics of the flue gas from the site. The flue stream would need to cool far more rapidly than is possible, even on the coldest of days, for any likelihood of it being “trapped at a low level.
