Abstract In this study, the Weather Research and Forecasting (WRF) model was applied to dynamically downscale the Parallel Climate Model (PCM) projection for the climate change impact on regional meteorological conditions in California. Comparisons were made for meteorological fields that strongly influence regional air quality between the current (2000–06) and future (2047–53) downscaling results to infer potential air pollution changes in California. Changes in both the meteorological fields and the implied future air quality vary by region and season. Analyses showed that the normalized number of stagnation days (NNSD) integrating all stagnation events, during which most of the air pollution episodes occur, in California's San Joaquin Valley (SJV) will increase and the intensity of stagnation will be stronger in the future for the two main air pollution seasons (i.e., summer and winter). Increases in surface wind and planetary boundary layer height (PBLH) were observed for the coastal part of Los Angeles County (LAC) during summer, suggesting stronger ventilation in this region. Contrary situations were seen in other parts of the South Coast Air Basin (SoCAB) and SJV. Although a surface wind change was not evident in SJV during winter, there was a significant PBLH decrease. Climatechangeinduced variations in surface wind and PBLH were only statistically significant in coastal SoCAB and the southern portion of SJV relative to the corresponding interannual variability; changes in temperature are significant throughout the regions studied. The sea breeze along the coast of California plays an important role in the state's climate and air quality, especially during summertime owing to the stronger intensity compared to wintertime. Analysis of the land–sea temperature contrast and the southwesterly wind along the California coastline indicated that the summertime sea breeze will be stronger in the Central Valley (CV) but weaker for the SoCAB region in the future.

The Impact

The purpose of this work is to review and analyze the main results of modern research on the impact of climate change on the agro-sphere of Ukraine. Results. Analysis of research has shown that the effects of climate change on the agro-sphere are already being felt today and will continue in the future. The observed climate changes in recent decades have already significantly affected the shift in the northern direction of all agro-climatic zones of Europe, including Ukraine. From the point of view of productivity of the agro-sphere of Ukraine, climate change will have both positive and negative consequences. The positives include: improving the conditions of formation and reducing the harvesting time of crop yields; the possibility of effective introduction of late varieties (hybrids), which require more thermal resources; improving the conditions for overwintering crops; increase the efficiency of fertilizer application. Model estimates of the impact of climate change on wheat yields in Ukraine mainly indicate the positive effects of global warming on yields in the medium term, but with an increase in the average annual temperature by 2 ° C above normal, grain yields are expected to decrease. The negative consequences of the impact of climate change on the agrosphere include: increased drought during the growing season; acceleration of humus decomposition in soils; deterioration of soil moisture in the southern regions; deterioration of grain quality and failure to ensure full vernalization of grain; increase in the number of pests, the spread of pathogens of plants and weeds due to favorable conditions for their overwintering; increase in wind and water erosion of the soil caused by an increase in droughts and extreme rainfall; increasing risks of freezing of winter crops due to lack of stable snow cover. Conclusions. Resource-saving agricultural technologies are of particular importance in the context of climate change. They include technologies such as no-till, strip-till, ridge-till, which make it possible to partially store and accumulate mulch on the soil surface, reduce the speed of the surface layer of air and contribute to better preservation of moisture accumulated during the autumn-winter period. And in determining the most effective ways and mechanisms to reduce weather risks for Ukrainian farmers, it is necessary to take into account the world practice of climate-smart technologies.
