title: Hazardous Heavy Snowfall Events in the Ural region (Russia) in 1981 - 2025

description: the dataset consist of 116 heavy snowfall reports (snowfall intensity ≥ 20 mm 12 h<sup>-1</sup>), which have occurred in the Ural region in the period 1981 – 2025. They are associated with 56 different heavy snowfall events. Among them, there are 97 reports (48 events) of heavy snowfall and 19 reports (8 events) of heavy wet snow or snow mixed with rain (precipitation intensity ≥ 20 mm 12 h<sup>-1</sup>). For each report, the date and time of occurrence and WMO ID of the weather station are shown (except for several weather stations which ceased observations in the 1990s). 12-h and 24-h accumulated snowfall, and wind gusts (if available) are given for each reports. In addition, they are classified into 5 types by the air mass origin according to the 72-h backward trajectories according to the NOAA HYSPLIT model. There are S type (southern advection from the Caspian or Aral Seas); SW type (southwestern advection from the Black or Mediterranean Seas), W type (western advection from the Baltic, North and Norwegian Seas); NW type (northwestern advection from the Barents Sea) and local type (when there is hard to identify the moisture source).

title: Table 5 Replication Data

description: We conducted a validation exercise with two goals. First, to assess the <i>generalizability of our spatial ontology </i>to new datasets and second, to assess the <i>quality of geocoded routes </i>when compared against ground truth reports of congestion. The results presented in this paper pertained to tweets from the DTP, a single user that posts mostly traffic-related tweets from a single geography - Delhi NCR. We assess the generalizability of our spatial ontology beyond both a specific geography and a single user. We apply the ontology to extract spatial information from a dataset of New Jersey, USA containing a mixture of traffic-related and unrelated tweets posted by multiple users (Dabiri 2018). We classified each tweet into a spatial configuration without relying on gazetteer lookups or doing route computations since the goal here is only to assess whether the ontology adequately captures the spatial information present in the data. We hypothesize that traffic-related tweets will tend to contain “more” spatial information as compared to non-traffic related tweets. We test this assigning spatial information scores (SIS) to each configuration as follows. <b>Unclassified</b> → <b>0</b> (noise, little or no recoverable spatial information).<b>Primitive configurations</b> <b>P, O, D</b> → <b>0.5</b>. These provide collocation or a single locational cue but do not specify spatial relationships, flow or movement.<b>Complex configurations</b> <b>MP, L, ML, PonL, P&D, O2D, O2MD, O2D@P, O2DonL</b> → <b>1</b>. These express direction, adjacency and/or parallel linear orientation and, for the O2D family, movement along a route.We then define the <i>spatial information index</i> (SII) for a dataset with N tweets as:SII = 1Ni=1NSISiThe spatial information index (SII) is the total normalized spatial information score for all the tweets in a dataset. According to our hypothesis, the SII should be higher for specialized datasets containing traffic-related tweets and lower for non-traffic related tweets and noisy datasets containing mixed tweets. The spatial information index is thus intended to measure the sensitivity of our ontology to the spatial information intrinsically present in data.  The results of validation are shown in Table 5.
