古土壤、古岩溶和大气成岩作用类型的证据表明，英国南部早石炭世气候以季节性半干旱为主。这种半干旱发生时，该地区是在赤道palaeolatitudinal位置。季节性干旱的原因可能是东风转向到一个主要的低气压区成立于冈瓦纳在南半球的夏季。
Evidence from palaeosols, palaeokarsts and styles of meteoric diagenesis shows that the early Carboniferous climate of southern Britain was dominantly seasonally semi-arid. This semi-aridity occurred while the region was in an equatorial palaeolatitudinal position. The cause of the seasonal aridity was possibly the deflection of easterly winds into a major low pressure zone set up over Gondwana during the southern hemisphere summer.
