Instead of pleasant mornings, the Malayalam month of Chingom is likely to be marked with humid days and foggy mornings this year with a rise in temperature and humidity.
Already, the minimum morning temperature this month has set a new benchmark due to a ‘break in monsoon’. Indicating a shift in atmospheric conditions, a thin layer of fog enveloped the plains and hilly areas on Wednesday, reducing visibility to less than 500 metres in some areas.
“If the visibility is more than 1,000 metres, it is called mist, while fog indicates visibility falling to less than 1000 metres. Also, fog is a symbol of stability in atmospheric conditions (instability used to create rainfall). The appearance of fog at this point in time indicates subdued rainfall, reducing the chances for big spells in the coming weeks,” says a senior meteorological scientist.
