We left the village this morning, enveloped in a thick fog, anticipating its prompt dispersal under the forecasted sunshine. Soon, intermittent patches of blue sky overhead began to play a fickle game. Only as we finally ascended through the murky haze to Easby Moor at 324 metres asl., we found ourselves above the clouds, affording us a sporadic view of a vast sea extending towards the Cleveland Hills.
This meteorological quirk, as you might be aware, goes by the name of a temperature inversion. It transpires when the air cools upon encountering the chilly ground, a phenomenon most likely to occur in calm weather. Valleys become shrouded in clouds due to this cooling process.
Such climatic peculiarities are not uncommon in North Yorkshire. The liminal layer—where the warmer air above meets the cooler air in the valley—displayed an unusually turbulent and fragmented appearance. Nevertheless, it seemed to extend its influence over the entirety of the Vale of Cleveland.
