from topography, land use (e.g., forests, urban structures), and convection. Fig . 3. Depiction of a 3D mesonet observing system including a standard 10-m surface mesonet tower along with a WxUAS capable of sampling the complex kinematic and thermodynamic structure of the ABL. While WxUAS technology is still new for the application in this area, and no known mesonets have yet deployed WxUAS in an operational nature to collect such mesoscale observations, rapid developments are taking place. These

, the Parallel Climate Model (PCM) was used to complete climate simulations with the results then being downscaled to the appropriate location for each city. The PCM is a global coupled atmosphere–ocean general circulation model (AOGCM) developed at the National Center for Atmospheric Research (NCAR) that provides state-of-the-art simulations of the earth’s past, present, and future climate states. Included in the PCM is a series of submodels of the atmosphere, ocean, sea ice, and land. The

. 2016 ), such as the Canadian Alternative Land Use Services (ALUS) program for ecosystem service stewardship ( France and Campbell 2015 ). Other initiatives are more top-down, for instance, Canada’s Growing Forward (GF), 1 an investment package, policy framework, and federal–provincial–territorial partnership that aimed to encourage innovation and adaptability, including environmental stewardship, water management, and mitigation of greenhouse gas emissions ( Agriculture and Agri-Food Canada 2008

1. Introduction Where, when, and at what frequency lightning occurs across the globe is steadily becoming better known by the use of a variety of sensors ( Holle and Cooper 2016b ; Nag et al. 2015 ). Lightning is due to upward vertical motions accompanied by microphysical processes at elevations with typical ambient temperatures between −5° and −15°C. The upward motion resulting from vertical instability in the atmosphere can then become strong enough to produce lightning in the relevant

income ( ODFW 2017 ). In 2012, researchers worked with members of the commercial-fishing fleet from Newport, Oregon, as part of an effort to document and understand how they make strategic decisions using ocean condition forecasts ( Duncan 2014 ). Findings revealed that fishermen used a variety of data sources yet lacked a single trusted source, and that they were not utilizing the most advanced, publicly available regional forecasts due to the way that scientists presented the information ( Duncan

and demographic characteristics of communities, and 3) the physical infrastructure—buildings, roads, bridges, and other components of the built environment such as basements in the case of tornadoes ( Paul and Stimers 2014 ). Taking a holistic approach to local government policies concerning land use planning, warning and communication systems, building codes, and community hazard mitigation networks is key for improving safety. Research has examined the effectiveness of local government early

the Caribbean’s main generator of income during the colonial period after the “sugar revolution” ( Pons 2007 ). Furthermore, some authors contend that Caribbean sugar production yielded an exceptional “economic surplus” that contributed to the Industrial Revolution and growth in the metropolitan economies in colonial Europe ( Sheridan 1961 ; Williams 1944 ). The remainder of the paper is organized as follows. Section 2 outlines the data sources used, provides descriptive statistics, and

socioeconomic characteristics across the zones. We use longitudinal household-level socioeconomic data from the TIA to calculate changes in annual crop income, participation in different crop types, income shares from different crop types, land area under cultivation, and other characteristics of households over the 2002–05 time period. 2 The survey sample is nationally representative of small- and medium-scale farm households. 3 After eliminating extreme outliers and households that did not receive any

vulnerable to food insecurity because of communities’ limited capacities to adapt to environmental changes. During the last three decades or so, the southern Africa region has experienced frequent intense droughts ( Vogel et al. 2010 ; Rouault and Richard 2005 ) that have had a negative impact on regional food security. A few studies, using daily data, have been carried out in Zimbabwe (e.g., Makuvaro 2014 ; Mazvimavi 2010 ; Aguilar et al. 2009 ; New et al. 2006 ) to determine the trends in

hurricane winds at the land surface are highly turbulent because of interaction with the high friction land surface and damaging 3-s gusts can far exceed the mean wind speed ( Vickery et al. 2009 ). To explore sensitivity to the threshold wind speed, we define three physically based wind speed thresholds: hurricane force (33 m s −1 ) 1-min mean wind, a slightly reduced 1-min mean wind speed that can sustain 3-s hurricane force gusts (25 m s −1 ; using a gust factor of 1.3 following Vickery et al. 2009
