Early Friday morning, I received the news that some subway lines were suspended, and it was not destined to be a peaceful working day for ** people. The low temperature caused some of the subway to be frozen and unable to operate normally. The emergency start of public transportation, the launch of shared bicycles, and the ...... of territorial reinforcements in placeDespite this, the morning rush hour of tens of thousands of office workers was still affected.
At the G40 Yangtze River Bridge, due to low temperature icing, there were also a number of traffic accidents caused by vehicle skidding, and the traffic management department once closed the bridge to deal with the accident and carry out de-icing operations.
It must be said that in handling today's emergencies, the departments of transportation, road administration, public security, including the local streets and towns, have done their best, and they are also very effective. But when the people who struggled to arrive at the office saw the meteorological department's popular science about "there is no freezing rain in Shanghai", they must have a question in their hearts: the minimum temperature predicted today was about 1 degree, and it has not yet reached below freezing. Did the meteorological department foresee this "accident" for most people, and could it have been reminded earlier?
According to the meteorological department, there was no significant precipitation in Shanghai the night before, the surface temperature in most areas did not fall below 0 degrees Celsius, and freezing rain was indeed not detected at various observation points. However, it cannot be ruled out that some areas will freeze due to high humidity and open areas. Of course, the meteorological conditions from the night before to the early morning of the same day did not meet the conditions for the surface temperature to drop below zero in 48 hours, so they did not meet the criteria for frost and ice warnings.
Weather forecasts are not 100% accurate; It is not freezing rain and does not meet the frost warning standards, which is indeed the reason for the failure to predict the impact of low temperature in advance, but the impact of sudden weather on the travel of citizens in some areas is real. The establishment of the early warning system, in the final analysis, is to ensure the normal operation of the urban society and the safety of people's lives and property, if it is indeed foreseeable that sudden weather conditions may affect the operation of the city, even if it does not meet the early warning standards, even if it affects only the "local area", you can also pass a notice, a reminder, so that the "accident" becomes "no accident", so that the units and individuals that may be affected can deal with it more calmly. I remember that in the past typhoon season, we used to say that we would rather "take ten precautions and nine emptiness" than be fully prepared, because everyone understands that the cost of activating various plans before the situation occurs, and the risks faced by the masses must be the smallest.
Finally, it is necessary to praise the inspection system of Shanghai Metro, which can find the abnormality of touching the net and freezing in time before the operation of the first train, and quickly make decisions and start the emergency plan; I would also like to thank the public transportation, public security, and the protection of the local towns and towns. Although many people's commute to work has become a bit tortuous in the cold wind, everyone's safety is the most important thing.
