Com­ing win­ter is likely to have mild tem­per­a­ture pe­ri­ods

Hinckley Times - - LETTERS -

I READ the Hinck­ley Times ar­ti­cle of Novem­ber 1, “Fore­cast­ers say it could be a cold win­ter ahead” with puz­zle­ment, af­ter read­ing the World Me­te­o­ro­log­i­cal Or­ga­ni­za­tion ar­ti­cle of 6 Novem­ber, “2017 is set to be in top three hottest years, with record­break­ing ex­treme weather”.

A re­cent in­di­ca­tion of con­tin­ued Global Warm­ing was Trop­i­cal Cy­clone Ophe­lia.

On Mon­day 9 Oc­to­ber at 9am GMT a Trop­i­cal De­pres­sion was re­ported by the USA Gov­ern­ment Agency, Na­tional Oceanic and At­mo­spheric Ad­min­is­tra­tion, Na­tional Hur­ri­cane Cen­ter in Mi­ami, Florida; in the sub-tropic lat­i­tude of 31.1 north, track­ing north at a speed of three knots in the mid At­lantic Ocean west of Morocco, Africa and east of South Carolina, USA. At 3pm GMT on Satur­day 14 Oc­to­ber Ophe­lia had in­ten­si­fied to a cat­e­gory three ma­jor Hur­ri­cane while south of Ponta Del­gada and west of Ra­bat, Morocco.

At 3pm GMT Sun­day Ophe­lia had weak­ened to a cat­e­gory one Hur­ri­cane, west of Porto, Por­tu­gal and east-north­east of Ponta Del­gada, Azores: be­fore track­ing north-east to­ward The Repub­lic of Ire­land.

Ophe­lia hav­ing orig­i­nated from a Trop­i­cal Cy­clone in the sub­trop­ics lat­i­tudes con­tained a large amount of mois­ture, which when fall­ing as rain over­land, could have caused ex­ten­sive flood­ing, land­slides and a threat to life; how­ever most of the rain fell to the west of Ire­land over the At­lantic Ocean. The wind speed gust in ex­cess of 100mph near to the cen­tre of the storm caused struc­tural dam­age when mak­ing land be­fore weak­en­ing due to the land sur­face.

For a Trop­i­cal Cy­clone to have tracked so far north and east in the At­lantic Ocean is un­known in the past and could only be main­tained by a warm Sea Sur­face Tem­per­a­ture and a suit­able low wind gra­di­ent.

So the forth­com­ing win­ter al­though likely to have some cold pe­ri­ods with air flow­ing from the Arc­tic or Green­land, is also likely to have mild tem­per­a­ture pe­ri­ods with air flow­ing from the south-west warm At­lantic Ocean.
