    NOVEMBER 2021


    Thick fog blanketed Moscow from late Monday into Wednesday morning, causing hundreds of flights to be canceled in one of the biggest travel disruptions to impact the Russian capital in a decade (1st-3rd0. More than 200 flights were cancelled or delayed
    at Moscow's major airports on Tuesday. The delays appeared to be the most since an ice storm blanketed the city in December 2010. On Wednesday, the return of fog led to another 60 flight cancellations or delays. Visibility was quickly reduced on Monday
    evening when the fog first settled across the city. Observations from across the city showed that the visibility fell to near zero for as much as 14 consecutive hours. At several locations, temperatures fell below freezing overnight, which may have also
    led to ice forming on some surfaces.


    A severe dust storm that started in southern Kazakhstan hit parts of Uzbekistan in the evening, growing under favorable weather conditions into the worst since the country started keeping meteorological records in 1871 (4th). The worst affected were
    Tashkent and the southern Syrdarya Region, and Kazakhstan's Turkestan Region. According to the country's meteorological service - Uzhydromet, under the influence of gusts of wind, the parched upper layer of soil rose up, creating the effect of a dust and
    sand haze, with visibility just 100-200 m in a number of districts in the country.

    Heavy blizzards in some parts of north-eastern China have brought record snowfall, raising concerns about keeping homes warm in an area hit by power outages earlier this year (7th-11th). In the capital city of Shenyang, in Liaoning province, average
    snowfall reached 50 cm. This is the highest recorded snowfall since 1905, said state outlet Xinhua. In neighboring inner Mongolia, one person died and more than 5,600 were affected after a heavy snowstorm.

    Heavy showers and thunderstorms have caused severe flooding in the southern Indian city of Chennai (8th). No deaths have been reported, but officials in the state of Tamil Nadu, of which Chennai is the capital, have issued warnings to evacuate people

    Authorities in the Indian capital, Delhi, have shut all schools and colleges indefinitely amid the worsening levels of air pollution (17th). Construction work has also been banned until 21 November but an exception has been made for transport and defence-
    related projects. Only five of the 11 coal-based power plants in the city have been allowed to operate. A toxic haze has smothered Delhi since the festival of Diwali.

    At least 26 people have been killed and more than 100 remain missing after heavy rains caused massive floods in parts of Andra Pradesh, southern India over the past couple of days. Many homes, roads, and bridges have been damaged or destroyed and

    A potent storm system moving over the Sea of Japan brought heavy sea-effect snow to parts of Japan, in some areas breaking all-time 24-hour snowfall records (23rd-24th). Shumarinai recorded 77 cm of snow over 24 hours, setting its new all-time 24-hour
    snowfall record. Meanwhile, Nayoro registered 60 cm, setting its new 24-hour snowfall record for the month of November.

    Heavy rains affecting Bosnia and Herzegovina caused severe flash flooding in parts of the country, causing power outages and forcing evacuations (4th-5th). Hundreds of homes in the Sarajevo suburbs, along the rivers Bosnia, Tilava, and Zeljeznica, and in
    the southwest part of the country, around the town of Konjic, had to be evacuated on Friday under unrelenting heavy downpours that started falling on Thursday. Most parts of Sarajevo were left for hours without electric power on Friday morning due to the
    flooding of one of the main substations on the outskirts of the city.

    One person was killed and two others injured after a tornado hit the Italian island of Sicily (17th). The twister affected Trebalate, Serrameta, Sant' Elena, and Bosco in the southeast of the island, downing trees, collapsing walls, and causing a great

    A severe thunderstorm struck Malta in the morning, sweeping away cars in many parts of the country and blocking roads (25th). The worst affected were Msida, Gzira, Mosta, and Naxxar. Teams from Malta's civil protection, police, and military rescued
