The purpose of this study is to uncover the climatological characteristics of Yangganjipung, a strong local wind blowing in Yeongdong region, Korea, which has recently attracted attention as an exacerbation factor of wildland fire spread. Analyses of 20-year (2000-2019) surface climate data observed by the Korea Meteorological Administration demonstrate that strong westerly winds exceeding 20 m/s (25m/s in mountainous areas) more frequently occur in the northeastern coastal region (between Yangyang and Goseong) of Gangwon province rather than the southeastern coastal region, evidencing the existence of Yangganjipung. The intensification of Yangganjipung may be associated with the convergence of strong westerly winds along a southwest-northeast directional tectolinement connected to the western flank of the Taebaek Mountain Range. It is also notable that Yangganjipung tends to occur seasonally between late fall and late spring and diurnally between afternoon and nighttime hours. Examinations of the composited maps of NCEP-NCAR reanalysis data for multiple cases reveal that the formation of a low pressure anomaly core around northern East Sea provides the favorable condition for long-lasting, intense Yangganjipung occurrences. These results are expected to be used as the basic data for establishing a gusty wind warning system to prevent regional-scale climate disasters associated with Yangganjipung such as large-scale forest fires in the eastern coast of the Korean Peninsula.

The aim of this research is to analyze the level of food insecurity of Inuit in the area of Nunavut territory in Canada. As a result, we were able to find out the following facts. First, nearly half of them felt hungry due to lack of food as of 2018. Second, the food situation was getting worse year by year. In the four years from 2014 to 2018, the growth rate of food insecurity households reached 22.0%. Third, proportion of children under 18 who lived in food insecure households reached 78.7%. Starving children had low self-esteem, suffered from depression and had a very high suicide rate. Fourth, most of Inuit’s food tables were filled with store-bought foods, rather than country foods. Fifth, the food sovereignty of Inuit community was seriously threatened with local capacity of self-sufficiency being low, market-dependent being high, and political exclusion from the policy decision being severe. Two things needed to be kept in mind in order to solve this Inuit’s food insecurity efficiently. First, in addition to environmental factors such as climate change, food issues are interconnected and affected by socioeconomic, cultural and policy factors. Second, policy intervention in the food issues should be centered on the Inuit party in accordance with human rights and food sovereignty perspectives.

This study investigated the relationship analysis between wheat cultivated area and the climate data in Sindh province of Pakistan. The extraction of wheat cultivation area is detected using the remote sensing technique. The analysis of the study area reveals the annual mean maximum and the mean minimum temperature tends to risen with a large range of changes. The trend of average annual precipitation showed a large change, thus it was confirmed that the increase and decrease yield of wheat were depend on the various growth periods of wheat crop. The most influential factors are the annual mean precipitation and the annual mean minimum temperature at the seedling stage of wheat crop. The annual precipitation, annual mean maximum, and the annual mean minimum temperature are significant at the growth period. The annual mean maximum and the annual mean minimum temperatures are significant during the ripening stage of wheat crop in the study area. The results of the study showed that wheat production varies with climate change in the Sindh province. In addition, this study will be used as an important basis for solving crop cultivation areas and production problems caused by climate change in the region.

The Korean Peninsula has experienced regime shift (RS) in winter temperature since the mid-1980s. After the RS, monthly mean temperature significantly increased by 1.05°C in December with 95% confidence level, 1.36°C in January with 99% confidence level, and 1.60°C in February with 99% confidence level, respectively. Interestingly there is no RS in warm winter with 95% confidence level while there is a clear RS in cold winter with 99% confidence level, especially in December and January (DJ), indicating that the RS of winter temperature is mainly due to an abrupt temperature shift in December and January after the RS. Composite analysis suggests that abrupt shift in January after the RS is related to the reduction in sea level pressure (SLP) between Siberian high and Aleutian low, leading to anomalous southerly. However, abrupt shift in December is closely related to the propagation of Rossby wave spanning from the weakening of Ural high to negative anomaly over the North Pacific via high pressure anomaly over the Korean Peninsula, leading to adiabatic heating. Wave activity flux analysis suggests that the abrupt shift of DJ and the associated high pressure anomaly over the Korean Peninsula is induced by the propagation of Rossby wave spanning from North Atlantic Ocean to the Korean Peninsula via the Arctic, especially in cold winter.

This study examines the socio-environmental impacts of mobility on Inuit people and its consequences in the High Arctic region of Canada. Mobility is the part of Inuit culture, the Inuit people moved for hunting on familiar distances and sites that is the part of their life through generations. These patterns of mobility represent an admirable appreciation and familiar knowledge of the environment in the aboriginal people. The system of mobility as social change is related to the environmental stress, food shortage, fur-trade, construction of military bases, state policies, forced resettlement and non-renewable resources development projects in the Arctic region. Since 1950s, the Inuit of Canadian Arctic region have experience forcefully the mobilities in form of relocation, new-settlements, medical moves and residential schools as well as environmental mobility. The effects of relocation from their original lands have sustained through generations. There is another sad story of the DEW-line (Distance Early Warning) construction. The construction was started without any consent or notification to the local communities. Inuit people were displaced into other places with non-respectable way from their indigenous land. The residential school system was another a misfortune form of mobility which removed Aboriginal children from their parents and forcefully teach them ‘white manners’. This unfair treatment to the Inuit becomes big debate in the country from the several decades ago. Experience of mobility either it was due to relocation, displacement, individual or residential schools and mobility due to climate change are common story of Inuit people in the Arctic region of Canada. A number of families are still dealing with this intergenerational distresses.
