Published: July 2022

In this paper we examine the impact of extreme phases (El-Niño and La-Niña) of El-Nino- Southern Oscillation (ENSO) on the frequency, duration, magnitude and spatial coverage of Heat waves (HWs) computed using daily maximum temperature of 103 stations during the hot weather season (April-June or AMJ) for the period 1961-2020 and Cold waves (CWs) computed using daily minimum temperature of 86 stations during the cold weather season (December-February or DJF) for the period 1971-2020 from India. HWs are generally experienced over the north, north-west, central, east India and north-east Peninsula [together called core HW zone (CHZ)] with highest frequency during May. Whereas, the CWs are generally observed in the Core Cold Wave Zone (CCZ) which is nearly the same as CHZ but includes Jammu and Kashmir and excludes coastal Andhra Pradesh. The study observed noticeable decadal variation in the frequency, spatial coverage and area of maximum frequency both in the HW/SHW and CW/SCW days over the country. It was also observed that there is an appreciable increase (decrease) in the number of HW days during El-Niño (La-Niña) events. Severe Heat waves were more prominent (longest and hottest) in El-Niño years. Exactly opposite association was observed in case of CW days. El-Niño event mostly inhibits the CW activities in India. Significant increasing (decreasing) trends in the HW (CW) days were observed in many stations from CHZ (CCZ), which is in tune with similar trends observed over various other parts of the world. The possible physical mechanisms for the observed linkage of these temperature extreme events over the country with the El-Nino / La-Nina are also discussed in the paper.

Published: July 2022

En la zona central de Chile existe una población de gato colocolo (Leopardus colocola) con características únicas que recientemente llevaron a la propuesta de considerarla especie monotípica endémica del país. Lamentablemente, esta población enfrenta una serie de amenazas, particularmente evidentes en la Región Metropolitana de Santiago. A la vez, los esfuerzos de conservación se ven obstaculizados por la falta absoluta de datos específicos, de modo que actualmente no es factible evaluar el estado de conservación de L. colocola en Chile central. Presentamos evidencia audiovisual de cinco avistamientos de L. colocola en la Región Metropolitana, todos ellos obtenidos a través de observaciones directas. Proceden de distintos ambientes naturales: el félido fue observado en zonas de uso público y privado, en áreas que cuentan con algún tipo de protección y otras que no. Las amenazas directas para la especie se repiten independientemente de estos parámetros y comprenden perros domésticos que deambulan sin supervisión, el uso del fuego y el consiguiente riesgo de incendios forestales, la presencia de vehículos motorizados y grandes cantidades de basura, así como la prolongada sequía en Chile central. Demostramos que L. colocola sigue presente en la Región Metropolitana de Chile, donde tiene que hacer frente a una serie de condiciones que ponen en peligro su sobrevivencia a largo plazo. La totalidad de las amenazas descritas en este trabajo son de origen antropogénico y, por ende, está en nuestras manos mitigarlas. Para ello, se requiere de la inclusión de la población de la Región Metropolitana y alrededores, tanto a través de la educación como de la fiscalización.

Published: July 2022

A rare combination of anomalously cold air and rapidly falling snow produced a massive travel disruption in parts of the southeastern U.S. on 28 January 2014. Storm-total snowfalls were generally only 5 cm in the Birmingham, AL area, but most people were at work or school when the snow began. Due to icy roadways, thousands of people were forced to sleep in offices and schools, while many vehicles were abandoned on freeways and surface streets.
This event was a unique forecasting challenge in many aspects, especially for the southeastern U.S. In the 24 h leading up to the event, numerical model quantitative precipitation forecasting (QPF) was focused south of the main population centers where the main disruptions eventually occurred. A layer of very dry air was present up to 800 hPa, but saturation deficits were low due to the cold air. Radar data a few hours before the event provided some of the only tangible evidence that significant snow may occur. However, forecasters did not anticipate the havoc that would ensue from the relatively light snow accumulations.
In this paper, we examine the event, including the synoptic setup, vertical profiles of temperature and moisture, soil temperatures, numerical models, and radar data. On the early morning of 28 January, when school superintendents and business owners had to make decisions on whether to open, no warnings nor advisories were in effect for the majority of the Birmingham area, and the media indicated there would be no travel problems in Birmingham.

Published: July 2022

A 40-year climatology (1979–2018) is presented for long-track tornadoes in the United States using the Storm Prediction Center tornado database. Path length (PL) stratification thresholds are defined using characteristics of supercell storm evolution, and are categorized as: all (ALL), PL >0 mi or 0 km; short (S), PL <30 mi or 48.3 km; long (L), [30, 60) mi or [48.3, 96.6) km; very long (V), [60, 90) mi or [96.6, 144.8) km; extremely long (X), PL ≥90 mi or 144.8 km; and long-track sum (LVX), PL ≥30 mi or 48.3 km. Results show LVX tornadoes: a) made up <1% of all tornadoes; b) occurred east of the Rocky Mountains; c) were generally wider; d) caused disproportionate numbers of deaths and injuries; e) typically had damage ratings ≥F/EF2 (peak F/EF3); f) occurred more often with more deaths and injuries in the Southeast than in the Midwest or Great Plains; g) had larger area scale and Destruction Potential Index; h) occurred mostly in April and May versus May and June for S tornadoes; i) occurred primarily from midafternoon to early evening; j) had a peak formation hour at 1600 local solar time (also true for ALL S, V and X), though L tornadoes had a peak and secondary peak at 1800 and 1500, respectively; k) were less common during nighttime than S tornadoes; l) were more frequent during nighttime in the Southeast than nighttime in the Midwest or Great Plains; and m) occurred more often with tornado outbreaks.
Case Study of a Long-lived Tornadic Mesocyclone in a Low-CAPE Complex-terrain Environment

On 22 May 2008 a long-lived mesocyclone spawned an EF2 tornado over terrain as high as 2650 m MSL in southeastern Wyoming. The mesocyclone was part of an elongated, complex storm system that grew rather early in the day near a slow-moving warm front. The mesocyclone is unusual in that it persisted and became tornadic in rather cold (~7°C), saturated surface conditions in an environment with CAPE < 1000 J kg-1 and no surface-based convective inhibition. The mesocyclone intensified as its parent storm moved over terrain gradually ascending by ~1000 m, reaching a radar-estimated low-level horizontal shear as high as 84 m s-1 km-1. This fast-moving mesocyclone could be tracked by the nearest Doppler radar for over 90 min.
This paper examines the characteristics and the environment of this mesocyclone using both operational weather data and high-resolution numerical simulations. Near-surface radar observations and model output suggest that the formation and maintenance of the mesocyclone in this low-CAPE environment benefited from two terrain-related factors. One is the observed channeling of the low-level flow, locally enhancing the storm-relative helicity. The second is the presence, suggested by high-resolution simulations, of banners of high potential vorticity generated by the strong southerly flow shearing around the Colorado Front Range.
Precipitation Properties of Supercell Hook Echoes
Authors: Kumjian Matthew R. 
Published: July 2022

Recent studies have suggested that thermodynamic properties of supercell rear-flank downdrafts (RFDs) can affect whether or not tornadogenesis occurs. The thermodynamic characteristics of RFDs are determined in part by microphysical processes such as evaporation of raindrops and melting of hailstones. Whereas in situ measurements of hook-echo particle size distributions (PSDs) are exceedingly rare, polarimetric radars can be used to determine the bulk characteristics of these PSDs remotely. A preliminary analysis of polarimetric radar data from a small sample of supercell hook echoes reveals unusual drop size distributions compared to typical rainfall in Oklahoma, as well as spatially inhomogeneous structures. The inner edge of the hook echo is often characterized by low or moderate reflectivity factor at horizontal polarization (ZH), with very high differential reflectivity factor (ZDR), indicating a sparse population of very large drops. The southern and/or western (back) portion of the hook is characterized by moderate to high ZH and rather low ZDR, indicating a surplus of small drops and/or a lack of larger drops. Hypotheses explaining the unusual drop size distributions are presented. Additionally, the time evolution of these characteristics is explored using data collected with a special rapid scanning strategy.
Synoptic-Scale Precursors, Characteristics and Typing of Nocturnal Mesoscale Convective Complexes in the Great Plains
Authors: Milrad Shawn M. , Kelly Cailee M. 
Published: July 2022

Mesoscale convective complexes (MCCs) occur frequently during the warm season in the central U.S. and can produce flooding rains, hail and tornadoes. Previous work has found that the synoptic-scale environment can greatly affect, and be affected by, the development and maintenance of MCCs. Ninety-two MCC cases from 2006-2011 are manually identified using infrared satellite imagery and partitioned into three types (upstream trough, zonal and ridge) using a unique manual synoptic typing based on 500-hPa height patterns. Upstream trough cases feature an amplified longwave 500-hPa trough upstream of the MCC genesis region (GR), while the 500-hPa flow is relatively flat in zonal cases, and a strong 500-hPa ridge is present over the Rockies in ridge cases. Individual case and storm-relative composite analyses of a subset of 28 cases show that of the three types, upstream trough cases feature both the strongest quasigeostrophic forcing for ascent and lower-tropospheric frontogenesis, the latter of which enhances ascent and is associated with a strong southerly low-level jet (LLJ). Zonal and ridge cases feature smaller magnitudes (in descending order) of all ascent-forcing parameters. Ridge cases, in particular, are characterized by weak Q-vector convergence, but easterly upslope flow likely acts as a compensating ascent mechanism. A thermodynamic analysis shows that high-θe air is advected into the GR in all three MCC types, and serves as fuel for development and maintenance. However, while the southerly LLJ advects high-θe air from the Gulf of Mexico in the upstream trough and zonal cases, such air is already pooled in the High Plains in the ridge cases and advected into the GR by easterly flow. In accordance with the synoptic-dynamic analysis, upstream trough cases have the longest duration and largest impact on the synoptic-scale environment, while ridge cases are the shortest-lived. The various underlying precipitation structures of each group are also explored; zonal cases, for example, appear to preferentially be associated with bow echoes.
