“…Results in Szeto (2008) and Szeto et al (2015Szeto et al ( , 2016 show that significant correlations are exhibited between hydroclimate variables in the domain and the intensities of these seasonal circulation features. In addition, cold-and warmseason extreme conditions are often associated with intense respective circulation anomalies as reflected in extremity of the corresponding PNA and H indices that measure the intensity of these circulation anomalies.…”

“…In accordance with the objectives of CCRN, we will focus on intra-annual timescales where the large-scale circulation variability exerts the most direct influences on hydroclimate extremes within the domain. In particular, emphases are placed on the analysis of future changes in the Pacific North American (PNA) pattern (Wallace and Gutzler, 1981) which strongly affects the cold-season climate of the region (see for example Table 2 of Szeto, 2008) and quasi-stationary upper-air circulation features over the northwestern USA that exert strong influences on the hydroclimate of southwestern Canada during the warm seasons (Shabbar et al, 2011;Brimelow et al, 2015;Szeto et al, 2015Szeto et al, , 2016.…”

“…As shown in Shabbar et al (2011), Brimelow et al (2015), and Szeto et al (2015Szeto et al ( , 2016, the tracking and development of synoptic systems that affect significantly the warm-season hydroclimate of southwestern Canada are strongly affected by the large-scale upper-level pressure anomaly over the northwestern US. In particular, anomalously wet (dry) conditions are typically found to be associated with upper low-(high-)pressure anomalies over the region.…”

Abstract. The interior of western Canada, up to and including the Arctic, has experienced rapid change in its climate, hydrology, cryosphere, and ecosystems, and this is expected to continue. Although there is general consensus that warming will occur in the future, many critical issues remain. In this first of two articles, attention is placed on atmospheric-related issues that range from large scales down to individual precipitation events. Each of these is considered in terms of expected change organized by season and utilizing mainly “business-as-usual” climate scenario information. Large-scale atmospheric circulations affecting this region are projected to shift differently in each season, with conditions that are conducive to the development of hydroclimate extremes in the domain becoming substantially more intense and frequent after the mid-century. When coupled with warming temperatures, changes in the large-scale atmospheric drivers lead to enhancements of numerous water-related and temperature-related extremes. These include winter snowstorms, freezing rain, drought, forest fires, as well as atmospheric forcing of spring floods, although not necessarily summer convection. Collective insights of these atmospheric findings are summarized in a consistent, connected physical framework.

“…However, the knowledge and capabilities to identify these relationships have increased. Recent work has shown that several droughts, including events in Ethiopia and Southern Africa (Funk et al 2016), Indonesia (King, Karoly, and Jan Van Oldenborgh 2016), western Canada (Szeto et al 2016), and the California drought (Griffin and Anchukaitis 2014; Williams et al 2015), were worsened by climate change.…”

Extreme weather and climate events affect human health by causing death, injury, and illness, as well as having large socioeconomic impacts. Climate change has caused changes in extreme event frequency, intensity, and geographic distribution, and will continue to be a driver for change in the future. Some of these events include heat waves, droughts, wildfires, flooding rains, coastal flooding, surges, and hurricanes. The pathways connecting extreme events to health outcomes and economic losses can be diverse and complex. The difficulty in predicting these relationships comes from the local societal and environmental factors that affect disease burden.

“…Global warming and erratic rainfall have substantial negative effects on agriculture, lowering yield and reducing production (Bonsal et al, ). Drought is thus becoming one of the major factors threatening food security (Bonsal et al, ; Szeto, Zhang, White, & Brimelow, ). The waxy cuticle that covers the primary aerial surfaces of land plants plays an important role in plant protection against environmental harm, including drought (Dominguez, Heredia‐Guerrero, & Heredia, ; Fernandez, Guzman‐Delgado, Graca, Santos, & Gil, ; Kosma et al, ; Samuels, Kunst, & Jetter, ).…”

Arabidopsis eceriferum (cer) mutants with unique alterations in their rosette leaf cuticular wax accumulation and composition established by gas chromatography have been investigated using attenuated total reflection (ATR)‐Fourier transform infrared (FTIR) spectroscopy in combination with univariate and multivariate analysis. Objectives of this study were to evaluate the utility of ATR‐FTIR for detection of chemical diversity in leaf cuticles, obtain spectral profiles of cer mutants in comparison with the wild type, and identify changes in leaf cuticles caused by drought stress. FTIR spectra revealed both genotype‐ and treatment‐dependent differences in the chemical make‐up of Arabidopsis leaf cuticles. Drought stress caused specific changes in the integrated area of the CH3 peak, asymmetrical and symmetrical CH2 peaks, ester carbonyl peak and the peak area ratio of ester CO to CH2 asymmetrical vibration. CH3 peak positively correlated with the total wax accumulation. Thus, ATR‐FTIR spectroscopy is a valuable tool that can advance our understanding of the role of cuticle chemistry in plant response to drought and allow selection of superior drought‐tolerant varieties from large genetic resources.
