“…Furthermore, this seasonal predictability can contribute to the forecasting of atmospheric extremes as well as fluctuations in marine resources. For example, MHWs generated in the South Sea in summer can induce atmospheric heat waves on the Korean Peninsula [53]. Therefore, the significant regional and seasonal differences in the mechanism underlying MHW onset can provide a starting point for understanding the air-sea interaction between extreme climate events.…”

Characteristics of marine heatwaves (MHWs) in the East Asian Marginal Seas (EAMS) were investigated using the daily Optimum Interpolation Sea Surface Temperature for 37 years (1982–2018), focusing on seasonal changes and regional differences. The summer MHWs occur 54% more frequently (2.7 events/decade) in a relatively wide area than in other seasons. The strong (up to 3.7 °C), long-lasting (up to 38 days/event) winter MHWs are concentrated along the subpolar front (SPF) in the East/Japan Sea (EJS) where the MHWs are 20% longer (2.2 days/event) than in the Yellow and East China Seas (YECS). The summer MHWs are primarily driven by increased shortwave radiation associated with reduced cloud cover and latent cooling from the weakened wind over the western flank of developing subtropical highs. Driving mechanisms of the winter MHWs differ by region. The YECS MHWs occur mainly due to the atmospheric processes associated with weakening continental highs while the EJS MHWs are largely driven by the northward shift of the SPF. Although large-scale atmospheric processes primarily drive the summer MHWs occurring in a wide area in the EAMS, our findings suggest that ocean processes can be a major contributor to intensified MHW generation in limited areas especially in winter.

“…The occurrence of warm episodes has been linked to sea surface temperature (SST) anomalies and both local and remote conditions (Purich et al, 2014) but are mainly focused on oceanic scales (Deng et al, 2018;Ham & Na, 2017). Air masses leading to temperature extremes in the Western Mediterranean region are first transported from the north Atlantic towards Europe for all categories.…”

Climate change is the most important environmental problem facing humanity in this century. And it has become the great axis of public policies and private actions in developed societies. The effects of altering the planetary energy balance due to anthropogenic greenhouse gas emissions are already becoming evident in some regions of the planet. Among them, the evidence is already significant in the areas with a Mediterranean climate. This paper collects, as a review paper, the evidence and trends that are being recorded in two areas with a Mediterranean climate (the Spanish Mediterranean coast and the central sector of Chile) to assess the effect of the global warming process. The impact that the current climate change is having on the main elements of the climate and on specific environmental processes in both of these geographical spaces has been analysed. The study seeks to update, through an evaluative summary, the state of the issue of climate change in Mediterranean areas, indicating its future impact on elements of the natural environment and on the functioning of the societies that exist in these regions.

“…Moreover, recently published studies show that increases in heat wave events over South Korea, East Asia, and Eurasia could be induced by anthropogenic global warming (Barriopedro et al, 2011;IPCC, 2013;Min et al, 2014;Tang et al, 2014;Min et al, 2015;Shin et al, 2018). There are relatively various mechanism studies on record breaking heat waves in Eurasia and United States, which are mainly induced by natural internal atmospheric variability with blocking event (Dole et al, 2011;Lau and Kim, 2012), dry land surface processes (Weisheimer et al, 2011), reduced ice and snow (Tang et al, 2014), anomalous atmospheric planetary waves (Teng et al, 2013), a Rossby wave train induced by strong convection in tropical Atlantic (Trenberth and Fasullo, 2012), snow-darkening effect (Lau et al, 2018), and local sea surface temperature forcing (Ham and Na, 2017). Nevertheless, the mechanisms explaining the generation and duration of the heat waves in South Korea have not been fully explored.…”

We investigate the impact of the diabatic heating (Q1) over the Indian subcontinent and Tibetan Plateau (TP) sensible heat on the heat waves in South Korea in July and August over a recent 42‐year period. In particular, we emphasize the role of the convective activity across the region from northeastern Pakistan to northwestern India (PWI) induced by the heat from the TP, especially over the western and eastern TP. A composite analysis indicates that the composite differences between the heat‐wave summers (HWS) and non‐heat‐wave summers (NHWS) resemble the circum‐global teleconnection (CGT) pattern, which generates a high‐pressure anomaly over the Korean Peninsula, producing favourable conditions for heat waves in South Korea. The first coupled mode of the geopotential height at 250 hPa with the daily maximum temperature (TM) for July and August in South Korea is consistent with the composite pattern, suggesting that the diabatic heating over the Indian subcontinent induces a high‐pressure anomaly over the Korean Peninsula through a CGT‐like mechanism. The regression analysis of the wind vectors in the upper troposphere also indicates that the diabatic heating over the PWI region and associated TP sensible heating generates the strong convection over the PWI region, which corresponds to the anomalous anticyclonic circulation at 250 hPa over the western TP and the cyclonic circulation at 850 hPa over the PWI region. Moreover, the correlation patterns of the 250‐hPa geopotential height with the normalized rainfall amount index (IMRI) over the PWI region and the wave activity flux pattern confirm that the strong convective activity over the PWI region contributes to the anomalous high pressure and heat waves over the Korean Peninsula.
