“…For each 1 °C increase in T avg during RGS and RGS 1 , yield changed by -6.82% to 5.74% and 1.77% to 10.12%, respectively. This result was consistent with the finding in some other researches [7,17,18], which suggesting that temperature was above the optimal temperature of rice production and increasing temperature might reduce yield. However, T avg during RGS 2 and RGS 3 were significantly positively related to rice yield in some regions, which was consistent with other studies [12,19].…”

“…In this study, results indicated that an increase in DTR during RGS 1 caused a significant negative effect on rice yields in most study areas. The reason might be that increase in the maximum temperature results in reductions in photosynthetic rates or increasing water stress [7,22,23]. However, an increase in DTR during RGS 2 and RGS 3 caused a significant positive effect on rice yields at most areas, which because cooling nights reduces the respiration rate and warming days increases photosynthetic rate [24].…”

“…Some recent studies also pointed out that crop yields are not always negatively associated with an increased average temperature based on site observations in China [10][11][12]. Such observations are inherently inconclusive and dependent upon the selection of sites, thus making them difficult to represent a regional situation [7].…”

“…Changes in temperature from 1981 to 2000 in China had accelerated rice phenological development and decreased rice yields based the data collected at experimental stations [7]. Rising average temperatures from 1961 to 2010 resulted in decreased maize yield in most region of China and decreased winter wheat…”

Sichuan province is one of the 13 major grain-producing provinces in China and also an obvious region of climate change. In this study, the responses of single cropping rice yields to climate variables under climate change at each development stage were investigated by using the linear regression method based on yield and climate data at 84 counties in Sichuan province of China from 1981 to 2012. The results indicated that change of all climate variables (increase of average temperature and diurnal temperature range, and decrease of precipitation and solar radiation) during different development stages in recent 30 years caused significant change of yield in less than 10% of the rice planting area. However, climate change from 1981 to 2012 had caused significant impacts on rice yield in roughly 47.6% of the rice area, with yields fluctuating by -11.77% to 24.55%. Moreover, average temperature was the most key contributor for the impact on rice yields in all climate variables and solar radiation was the most key contributor for the negative impact on rice yields. The empirical findings presented here provide a foundation for anticipating climate change impacts on rice production.

ResumoO objetivo do trabalho foi calcular as estatísticas descritivas para caracterizar a climatologia da temperatura mínima de relva, a mínima do ar a 5 cm do solo coberto com grama (Tmr), em Santa Maria (RS), associar a variabilidade interanual desse parâmetro com o fenômeno ENOS e verificar se há tendência de alteração na série histórica deste elemento meteorológico. Foram usados dados diários de temperatura mínima de relva, medidos no período de 1. o de maio de 1970 a 31 de dezembro de 2009, registrados na Estação Climatológica Principal de Santa Maria (latitude: 29º43'S, longitude: 53º43'W e altitude: 95 m). Classificaram-se os anos em anos de El Niño (EN), La Niña (LN) e Neutros (N), considerando-se o período de 1. o /7 a 30/6 do ano seguinte. A média mensal de temperatura mínima de relva variou de 6,9 ºC em julho a 17,3 ºC em janeiro, com mínima absoluta de -8,4 ºC em junho e máxima absoluta de 28,6 ºC em outubro. Há sinal do ENOS sobre a temperatura mínima de relva nos meses de outono, inverno e primavera, de modo que esta é maior em anos de EN, menor em anos de LN e intermediária em anos Neutros. Houve aumento na temperatura mínima de relva no período de 1970-2009 em abril, junho, outubro, novembro e dezembro, com início do aumento principalmente na década de 80. Nos demais meses não foram verificadas significativas tendências de ordem climática.Palavras-chave: El Niño, La Niña, variabilidade climática, mudança climática, tendência das mínimas.Minimum temperature over short grass in Santa Maria, RS: climatology, interannual variability, and historical trend AbstractThe objective of this study was to calculate the descriptive statistics to characterize the climatology of minimum air temperature at 5 cm over short grass (Tmr) in Santa Maria, RS. A further objective was to associate the interannual variability of Tmr with the ENSO phenomenon and also to verify if there is a trend in the historical series for this meteorological variable. Data used in this study were daily minimum air temperature over short grass measured at the Meteorological Station in Santa Maria, RS, Brazil (29º43'S, 53º43'W and altitude of 95 m) from
