  • Report 報告

    This week it was relatively wet and cloudier. On Sunday, it was cool and cloudy with some mist in the morning. As affected by a ridge of high pressure, it turned to be fine with air temperature rising to over 20 degrees. On Monday, a broad cloud band covered southeastern China. It was cloudy with sunny periods over the district. That night onwards, it became misty under the effect of a moist maritime airstream. For the next few days, that maritime airstream persisted to affect the South China coastal areas. It was cloudy to overcast with some fog and drizzle in the district. During the weekend, a trough of low pressure formed along the coastal areas. It then became a stationary front. That day morning, fog over the district once disappeared and it turned to be brighter. However, it again became cloudy in the afternoon. The stationary front was expected to become a cold front. And its associated northeast monsoon would spread southwards and brought significant cooler weather to the district in the coming few days.
