Descriptive Essay On Bad Weather. Leaving one questioning and unknowing of their surroundings, mystery, a feeling well known throughout all of mankind, causes one to become flustered at their surroundings and leave little knowledge available to integrate into situations. Surprising and bewildering, bad weather, an overcast through the world set
In hot weather, the overhead lines that provide power to the trains can expand and sag. To avoid damaging the lines, trains must travel more slowly. If the overhead lines are damaged, we have to cancel or divert train services until they are fixed. This causes delays. Modern overhead lines, which are used on the majority of Britain's rail
The FAA also helps pilots and airports determine if conditions are safe. Airlines will cancel flights if the weather makes for truly dangerous flight conditions. In most major airlines, pilots have thousands of hours of flying experience and training for flying in a variety of weather conditions, including snow and thunderstorms.

Smoky scenes â so common in California during recent summers â are now paying the eastern United States an unwelcome, improbable and toxic thick veil of Canadian wildfire smoke is spreading south over much of the Midwest, Ohio Valley, Northeast and Mid-Atlantic, bringing milky-white skies and dangerous air pollution to the most populous corridor of the country. Fine particles contained within the smoke, hazardous to breathe, have prompted air quality alerts for tens of millions of people from South Carolina to New of Tuesday evening, New York City had the worst air quality in the world among major cities. Scenes from social media and web cameras showed the sky above Manhattan tinged a reddish-orange hue, drawing comparisons to Mars.âIf youâre a New Yorker with heart or breathing issues, be careful when youâre outdoors,â said the City of New York in a tweet signed by the mayor. âSmoke from wildfires in Canada is impacting our cityâs air, so an Air Quality Health Advisory has been issued. Try to limit outdoor activities today to the absolute necessities.âThe haze and smell of smoke from the Canadian wildfires hung heavy over New York, raising concerns about air quality June 6.

Marshall Burke, a professor of environment at Stanford University, tweeted that this event is the â[n]ear worst or worst eventâ in the past two decades or so, based on smoke particle Haven, Conn., posted its worst air quality on record Tuesday while EPA measurements showed hazardous smoke pollution enveloping much of New York state and southern New are the wildfires causing the smoke?The source of much of the smoke pouring into the region is Quebec, Canada. Most broke out in the past week. Across Canada, there are 416 active fires, 240 of which the Canadian Interagency Forest Fire Center lists as âout of control.âThe wildfires cropped up beneath a well-predicted âheat dome,â or zone of high pressure, which brought sinking air and warm, dry conditions that broke records for the time of year and smoke from Canada continued to spread to the on June 6, creating hazy sunrises. Video The Washington PostLow pressure swirling counter-clockwise over Nova Scotia, meanwhile, is making for a conveyor belt of northerly winds that is pumping the smoke south over the Great Lakes, Northeast and is the smoke and where is it worst?Satellite imagery Wednesday morning showed smoke covering the Northeast and extending into the Carolinas.

ï»żAbstractRailway plays an indispensable role in long-distance passenger transport. Here, we investigate train exposure time to bad weather and its influence on an important railway operation problem, train delay. We find that train delay is more likely to occur in snow and rain weather and the total train delay time is in a good correlation with the train exposure time to bad weather. We also develop a train delay network to identify the communities of railway stations from the perspective of train delay co-occurrence. The obtained community structure can be potentially useful in designing regional management strategy for delayed is an important mode of long-distance passenger transport in China and many European countries. In 2016, railway transported billion passengers in China and billion passengers in Germany which respectively constituted and of all long-distance passenger trips in the two countries. The important role of railway transport in national economy and citizen benefits has attracted wide-spread attention from both academic and industrial weather is an important influential factor of railway operation [1], [2], [3]. On one hand, storm, strong wind, and heavy snowfall can cause train derailment [3], overturn [4], [5], [6], telecommunication interruption [7], [8], turnout freezing [9], and window breakage [6]. On the other hand, long exposure to rain and snow can accelerate the aging of railway infrastructure [10], [11], [12] and train equipment [13], [14]. Previous works have studied the correlation between railway operation and weather condition at the local railway line level [15], [16], [17]. However, the wide geographic layouts of railway network and the time-varying weather condition can result in heterogeneous train exposure time to a certain kind of bad weather. Therefore, it is necessary to pinpoint the trains that expose to bad weather for a long time, consequently investments and resources can be more inclined to the key part of a railway this study, schedule data and delay data of more than 7000 trains and weather report data of 344 cities in mainland China were collected. We analyze the train exposure time to different types of bad weather to uncover its correlation with train delay. We also identify the communities of railway stations from the perspective of train delay co-occurrence, which could be potentially useful in train delay management. Before introducing our methods and results, we first introduce the terminologies used in this studyService train/train A service train or a train does not represent the train vehicle traction vehicle, train carriage, etc.. Service train or train represents a set of connected train vehicles that complete fixed transport service. Each service train has a unique train number G83 and fixed trains Trains operate at a speed larger than 200 km/h. The train number of a high-speed train starts with the letter Gâ or the letter Dâ G83, D2002.Ordinary trains Trains operate at a speed lower than 200 km/h usually lower than 160 km/h. The train number of an ordinary train starts with a number or a letter other than Gâ and Dâ K198.Railway station/station A station where a train stops, railway passengers get off the train or get on the line Railway infrastructure connecting the railway stations. The railway line between two neighboring connected railway stations are defined as a railway schedule The scheduled arrival time of each train at each station that it stops time of a train at a station The actual train arrival time at a station minus the scheduled train arrival time at the delay time at a station The sum of the delay time of each train that stops by a snippetsRailway network dataThe schedule data of 7172 trains were collected from the official website of Railway Customer Service Center of China on December 28, 2017. The time that each train is scheduled to arrive at each station is recorded in this dataset. The geographical information system GIS data of 2763 railway stations were obtained from Tencent map, and the GIS data of the administrative areas of 344 cities were also obtained // train delay time at the railway station level and the service train levelBased on the train delay data collected, we estimate the total delay time Tdi of all trains stopping by a station i. The good positive correlation between the total delay time Tdi and the number of trains stopping by the station NVi indicates that big stations usually have large overall train delay time, which is of course consistent with our intuition Fig. 4a. However, the large average train delay time Tdi=TdiâNVi is more likely to be found at small railway stations with a small ConclusionsIn this paper, a systematic approach to analyze train exposure time to different types of weather is proposed. Train exposure times of more than 7000 thousand trains to snow and rain weather are analyzed, providing more comprehensive results than previous studies focusing on local railway lines. The train exposure time to the two focused bad weathers can be both approximated by power-law distribution with exponential truncation. Moreover, train delay time has relatively strong correlation is supported by the National Key Research and Development Program of China No. 2016YFB1200401, the National Natural Science Foundation of China No. 61473320, and the Project of Innovation-driven Plan in Central South University, China No. 2016CSX014.References 21 et effects on mid-latitude railways a statistical study of anomalies in the operation of signaling and train control equipment on the east-siberian railwayAdv.

To resolve this issue, it is necessary for railway managers to identify the factors that influence train delays infrastructure, timetable, and number of trains and to accurately predict train delays [3]. Train delay prediction in railway networks has been extensively studied using various traditional techniques [4]. First, analytic stochastic models, for example, different probability distribution models have been considered to measure the delay severity, including the Weibull, Chi-squared, Erlang, and log-normal distributions [5â7].View all citing articles on ScopusRecommended articles 6View full text© 2018 Elsevier All rights reserved.
