The Weather of November 2014

    The weather of November 2014 was overall cloudier yet warmer than usual.  The mean temperature for the month was 22.6 degrees, 0.8 degrees above the normal figure of 21.8 degrees.  Despite more clouds and less sunshine, the total rainfall of 31.1 millimetres recorded in the month was about 17 percent below the normal figure of 37.6 millimetres.  The accumulated rainfall since 1 January was 2593.6 millimetres, about 9 percent above the normal of 2371.7 millimetres for the same period.

    The month started off with mainly fine and warm weather in Hong Kong.  A cold front formed over the northern part of southern China and crossed the coast of Guangdong on 2 November.  The northeast monsoon behind the cold front brought cloudy and cooler weather as well as light rain patches to Hong Kong in the next couple of days.  With further replenishments of the northeast monsoon, the weather remained generally cloudy with a few rain patches until 14 November.

    After some early morning rain on 15 November, the arrival of a dry easterly airstream finally cleared the clouds during the day.  Under the influence of the dry continental air mass, the weather remained generally fine till 25 November.  A replenishment of the northeast monsoon brought the temperatures at the Hong Kong Observatory down to a minimum of 18.1 degrees on the morning of 18 November, the lowest of the month. 

    As a weakening cold front approached the south China coast, cloudy weather returned on 26 November with the strengthening of easterly winds.  The weather also became slightly cooler with a few rain patches on 27 November.  Under the influence of a moist easterly airstream, it remained generally cloudy with a few light rain patches till the end of the month.
