The Future of Midlatitude Cyclones
Current Climate Change Reports https://doi.org/10.1007/s40641-019-00149-4 MID-LATITUDE PROCESSES AND CLIMATE CHANGE (I SIMPSON, SECTION EDITOR) The Future of Midlatitude Cyclones Jennifer L. Catto1 & Duncan Ackerley2 & James F. Booth3 & Adrian J. Champion1 & Brian A. Colle4 & Stephan Pfahl5 & Joaquim G. Pinto6 & Julian F. Quinting6 & Christian Seiler7 # The Author(s) 2019 Abstract Purpose of Review This review brings together recent research on the structure, characteristics, dynamics, and impacts of extratropical cyclones in the future. It draws on research using idealized models and complex climate simulations, to evaluate what is known and unknown about these future changes. Recent Findings There are interacting processes that contribute to the uncertainties in future extratropical cyclone changes, e.g., changes in the horizontal and vertical structure of the atmosphere and increasing moisture content due to rising temperatures. Summary While precipitation intensity will most likely increase, along with associated increased latent heating, it is unclear to what extent and for which particular climate conditions this will feedback to increase the intensity of the cyclones. Future research could focus on bridging the gap between idealized models and complex climate models, as well as better understanding of the regional impacts of future changes in extratropical cyclones. Keywords Extratropical cyclones . Climate change . Windstorms . Idealized model . CMIP models Introduction These features are a vital part of the global circulation and bring a large proportion of precipitation to the midlatitudes, The way in which most people will experience climate change including very heavy precipitation events [1–5], which can is via changes to the weather where they live. -

This is a collaborative effort primarily between the Western Pacific Regional Fishery Management Council, NMFS-Pacific Island Fisheries Science Center, Pacific Islands Regional Office, Division of Aquatic Resources (HI) Department of Marine and Wildlife Resources (AS), Division of Aquatic and Wildlife Resources (Guam), and Division of Fish and Wildlife (CNMI). This report attempts to summarize annual fishery performance looking at trends in catch, effort and catch rates as well as provide a source document describing various projects and activities being undertaken on a local and federal level. The report also describes several ecosystem considerations including fish biomass estimates, biological indicators, protected species, habitat, climate change, and human dimensions. Information like marine spatial planning and best scientific information available for each fishery are described. This report provides a summary of annual catches relative to the Annual Catch Limits established by the Council in collaboration with the local fishery management agencies.

Dezember 2014 Abstract Wind storms globally pose the most important natural hazard from a socio-economic per- spective. For the European continent, it is especially winter storms related to synoptic- scale extra-tropical cyclones that often affect several countries at the same time bearing high risk of cumulative loss. Societal and economic stakeholders are interested in differ- ent aspects regarding these phenomena. On the one hand, (re-)insurance loss modeling requires high spatio-temporal resolution information for winter storms that happened in the past as well as physically consistent scenarios of storm events that could happen. On the other hand, socio-economic planning activities would benefit from any reliable information regarding the frequency of damage-prone storm events for the upcoming seasons and years. The current thesis addresses three aspects in this context: (i) It further develops an objective impact-oriented identification scheme regarding such wind storms. -

PERILS Press Release
PERILS PUTS INITIAL LOSS ESTIMATE FOR EXTRATROPICAL CYCLONE EGON AT EUR 212 MILLION Zurich, 23 February 2017 – PERILS, the independent Zurich-based organisation providing industry-wide catastrophe insurance data, has today disclosed its initial loss estimate for extratropical cyclone Egon which affected France and Germany on 12 and 13 January 2017. The low-pressure system associated with Egon developed as a secondary low from a large depression named Dieter and travelled rapidly in an easterly direction over northern France and Germany on 12 and 13 January 2017. High winds which occurred to the south of the system predominately affected northern and central France, as well as central and southern Germany. The cold front associated with Egon also resulted in heavy rain and snowfall. PERILS’ initial estimate of the insured property market loss for Egon is EUR 212 million. While the majority of the losses occurred in France and Germany, impacts were also felt in Austria, Switzerland and the Benelux states, albeit to a much lesser extent. PERILS’ market loss estimate for Egon is based on ultimate gross loss data as reported by primary insurance companies. In line with the PERILS reporting schedule, an updated estimate of the Egon market loss will be made available on 12 April 2017, three months after the event start date. Extratropical Cyclone Egon, maximum gust values in km/h: Egon occurred between 12 and 13 January 2017 and brought strong winds to northern and central France as well as central and southern Germany. Luzi Hitz, CEO of PERILS, commented: “Egon is the first European windstorm to exceed our reporting threshold of EUR 200m for this peril since Mike-Niklas in March 2015. -
Idealised Simulations of Cyclones with Robust Symmetrically-Unstable Sting Jets Ambrogio Volonté1,2, Peter A
Idealised simulations of cyclones with robust symmetrically-unstable sting jets Ambrogio Volonté1,2, Peter A. Clark1, and Suzanne L. Gray1 1Department of Meteorology, University of Reading, Reading, RG6 6BB, UK 2National Centre for Atmospheric Science-Climate, University of Reading, Reading, RG6 6BB, UK Correspondence: Ambrogio Volonté ([email protected]) Abstract. Idealised simulations of Shapiro-Keyser cyclones developing a sting jet (SJ) are presented. Thanks to an improved and accurate implementation of thermal wind balance in the initial state, it has been possible to use more realistic environments than in previous idealised studies. As a consequence, this study provides further insight in SJ evolution and dynamics and explores SJ robustness to different environmental conditions, assessed via a wide range of sensitivity experiments. 5 The control simulation contains a cyclone that fits the Shapiro-Keyser conceptual model and develops a SJ whose dynamics are associated with the evolution of mesoscale instabilities along the airstream, including symmetric instability (SI). The SJ undergoes a strong descent while leaving the cloud-head banded tip and markedly accelerating towards the frontal-fracture region, revealed as an area of buckling of the already-sloped moist isentropes. Dry instabilities, generated by vorticity tilting via slantwise frontal motions in the cloud head, exist in similar proportions to moist instabilities at the start of the SJ descent 10 and are then released along the SJ. The observed evolution supports the role of SI in the airstream’s dynamics proposed in a conceptual model outlined in a previous study. Sensitivity experiments illustrate that the SJ is a robust feature of intense Shapiro-Keyser cyclones, highlighting a range of different environmental conditions in which SI contributes to the evolution of this airstream, conditional on the model having adequate resolution.
