Rice (Oryza sativa L.) is a staple cereal crop and its demand substantially increasing with the growth of global population. Precisely predicting rice yields are vital importance to ensure food security in countries like China, where accounts for one-fifth total agricultural production. Previous studies found that had been significantly impacted by climate change. In addition, phenological variables were be important factors concerning due fundamental role carbon allocation between plant...

Global warming has been shown to affect weather and climate extremes, such as droughts, floods, windstorms, cold waves, heat waves. A number of studies have focused on the variability different characteristics these including their frequency, spatial extent, severity. Recently, study compound defined by co-occurrence multiple events with extreme impacts, attracted much attention. The dry hot is one type may lead detrimental impacts society ecosystem. Most previous changes in frequency or...

Timely and accurately predicting maize grain yields will contribute to making adaptive measures improve management practice adjust consumption patterns for ensuring food security. Unmanned aerial vehicles (UAV) are widely used obtain high-temporal high-spatial resolution remote sensing images of crops, enabling a possible sensor performance comparison. To date, few studies have compared the potential abilities multispectral-based hyperspectral-based images, only sensitive spectral wavelength...

Global warming has led to substantially earlier spring leaf-out in temperate-zone deciduous trees. The interactive effects of temperature and daylength underlying this response remain unclear. However, they need be accurately represented by earth system models improve projections the carbon energy balances temperate forests associated feedbacks Earth's climate system. We studied control using data from six tree species across 2,377 European phenological network (www.pep725.eu), each with at...

Compound dry and hot events (CDHEs) are commonly defined as occurrences of at the same time or in close succession. These have occurred frequently past decades caused great losses to multiple sectors including water security, food human health. This calls for an improved understanding their characteristics variations. study provides a database different characteristics, frequency, severity, duration, magnitude, variations CDHEs period 1951–2012 over global land areas. We first demonstrate...

Under global warming, dry and hot events have been increasing in recent decades are projected to increase the future across land areas. The impacts of compound may lead increased stress natural human systems than separate or events. Thus, quantitative assessments areas affected by these needed understand their risks.

Abstract Aim Vegetation phenology is highly sensitive to climate change. The timing of spring in temperate grasslands regulated primarily by temperature and precipitation. aim this study was determine whether the primary factor regulating vegetation has changed under ongoing change underlying mechanisms. Location Temperate semi‐dry China. Time period 1982–2015. Major taxa studied grassland. Methods We extracted start season (SOS) dates using five standard methods from satellite‐derived...

Abstract Weather and climate extremes, such as droughts heat waves, have been commonly characterized by different properties, including frequency, duration, magnitude. The magnitude is among the most important properties that determine impact of extremes. Compound dry hot events may cause detrimental impacts on water resources, energy security, crop production food receiving increasing attention in recent years. Although extensive studies conducted to investigate individual or evaluation...

Abstract The response of vegetation to climate extremes, including droughts and hot has been evaluated extensively in recent decades. However, quantitative assessments individual combined impacts dry conditions on are rather limited. In this study, we developed a multivariate approach for analyzing responses dry, hot, compound dry-hot from probabilistic perspective using precipitation, temperature, the Normalized Difference Vegetation Index (NDVI) period 1982 2015. Standardized Precipitation...
