During early 2020, the world encountered an extreme event in the form of a new and deadly disease, COVID-19. Over the next two years, the pandemic brought sickness and death to countries and their cities around the globe. One of the first and initially the hardest hit location was New York City, USA. This article is an introduction to the Special Issue in this journal that highlights the impacts from and responses to COVID-19 as an extreme event in the New York City metropolitan region. We overview the aspects of COVID-19 that make it an important global extreme event, provide brief background to the conditions in the world, and the US before describing the 10 articles in the issue that focus on conditions, events and dynamics in New York City during the initial phases of the pandemic.

An investment study sponsored by the New York City Economic Development Corporation with Intermodal Surface Transportation Efficiency Act of 1991 funds evaluated strategies for improving the movement of freight by rail to an 11-county subregion (including New York City) of the New York and northern New Jersey metropolitan area located east of the Hudson River. The major achievements of the process were the use of choice modeling techniques to understand the decision making of shippers and, in combination with other data sources, forecasting the demand for freight infrastructure investments. The methodologies described are applicable to the study of freight transportation investment strategies in many settings. The key finding of the analysis is that a rail freight tunnel would increase rail mode share relative to other alternatives and the so-called No Build case. The subregion east of the Hudson contains two-thirds of the region’s population, but it is at a significant disadvantage in the movement of freight relative to the subregion west of the Hudson. Rail accounts for only 2.8 percent of all the subregion’s shipments, compared to 15 percent within the subregion west of the Hudson. Two limited rail crossings of the Hudson River provide access to New York City and the rest of the east subregion. These conditions affect the level of truck traffic and air pollution within the subregion, the subregion’s overall economic competitiveness, and the viability of its port facilities. To address these concerns, four families of alternatives that could improve cross-harbor rail freight service were analyzed. Discussed is how the market demand for these alternatives was analyzed by linking six distinct methodologies and data sets: ( a) regional economic forecasts, ( b) commodity flow data, ( c) a modal diversion model, ( d) regional port forecasts, ( e) a regional travel demand forecasting model, and ( f) user benefit calculation models.

Abstract Damaging wind events not associated with severe convective storms or tropical cyclones can cause significant problems with transportation, infrastructure, and public safety over the northeastern United States. These nonconvective wind events (NCWEs) are difficult to forecast in New York City and surrounding regions as revealed by the relatively poor probability of detection (POD) and false alarm ratio (FAR) in recent years. This paper investigates the climatology of NCWEs between 15 September and 15 May over 13 cool seasons from 2000/01 through 2012/13. The events are separated into three distinct synoptic patterns: pre-cold-frontal (PRF), post-cold-frontal (POF), and nor’easter/coastal storm (NEC) cases. Relationships between observed winds and some atmospheric parameters such as 900-hPa geopotential height gradient, 3-h mean sea level pressure (MSLP) tendency, low-level wind profile, and stability are also presented. Overall, PRF and NEC have the largest FAR, because several events with a low-level jet at 1–2 km above the surface have relatively strong low-level stability that limits vertical momentum mixing. The POD is lowest for the POF events, which have a strong diurnal influence given the relatively deep mixed layer. Verification is also conducted over the cool seasons from 2009/10 to 2013/14 using the Short Range Ensemble Forecast (SREF) system from the National Centers for Environmental Prediction (NCEP). Both deterministic and probabilistic verification metrics are used to evaluate the performance of the ensemble during NCWEs. Although the SREF has more forecast skill than any of the deterministic SREF control members, it is rather poorly calibrated and exhibits a significant overconfidence given its positive wind speed bias in the lower troposphere.

The complexity of urban boundary layer dynamics poses challenges to those responsible for the design and regulation of buildings and structures in the urban environment. Lidar systems in the New York City Metropolitan region have been used extensively to study urban boundary layer dynamics. These systems, in conjunction with other sensing platforms can provide an observatory to perform research and analysis of turbulent and inclement weather patterns of interest to developers and agencies.
