The Tibetan Plateau (TP), which is well known as “The Third Pole”, is of great importance to climate change in East Asia, and even the whole world. In this paper, we selected the monthly temperature (including the monthly mean and the maximum and minimum temperature) during 1971–2015 from 88 meteorological stations on the TP. The data were tested and corrected by using Penalized Maximal F Test ...

Identifying the temperature change at a regional level is one of essential parameters to determine intensity climate change. The current investigation provides an examination changing trends in Punjab province from 1970 2019. Sen's slope estimator method applied monthly data mean (Tmean), maximum (Tmax), and minimum (Tmin) calculate rate Statistical methods were used find out significance terms...

Previous research has documented a tight positive relationship between vegetation activity and growing season air temperature in China’s temperate zone (TC). However, this may change over time following alternations other environmental factors. Using the linear regression analysis moving windows based on partial correlation method, temporal variations of responses NDVI to rising during 1982–201...

Precise estimation of reference evapotranspiration (ET0) is significant importance in hydrologic processes. In this study, a genetic algorithm (GA) optimized back propagation (BP) neural network model was developed to estimate ET0 using different combinations meteorological data across various climatic zones and seasons China. Fourteen locations were selected represent five major climates. Mete...

Abstract This study analyzes the long‐term observed changes of mean (Tmean), maximum (Tmax) and minimum (Tmin) air temperatures, relative humidity (RH) vapour pressure deficit (VPD) at different elevation ranges across Bolivia from 1950 to 2019. The linear trends in temperature series present a significant increase, with no substantial seasonal or spatial differences. On an annual basis, RH exh...

Fraction of exhaled Nitric Oxide (FeNO) is a marker airway inflammation. We examined the main effects and interactions relative humidity (RH) air pollution on adolescents’ FeNO. Two thousand forty-two participants from 15-year follow-up German GINIplus LISA birth cohorts were included. Daily meteorological (maximum [Tmax], minimum [Tmin] mean [Tmean] temperatures RH) [Ozone (O3), nitrogen dioxi...

an increase, even moderate, in global temperature is expected to result in a change in frequency of extreme weather events like drought, heavy rainfall and storms. the study of extreme events is difficult due to the fact that it is difficult to find long-term homogeneous data series. also the delimitation of extreme events is not univocal since a parameter value that would be defined as an extr...

Crop phenology is considered to be an important indicator reflecting the biophysical and physiological processes of crops facing climate change. Therefore, quantifying crop change its relationship with variables great significance for developing agricultural management adaptation strategies cope global warming. Based on Moderate Resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation I...

Background The aim of this study was to construct an electronic bowel sound recording system and determine its usefulness for the diagnosis of appendicitis, mechanical ileus and diffuse peritonitis. Materials and methods A group of 67 subjects aged 17 to 88 years including 15 controls was examined. Bowel sounds were recorded using an electret microphone placed on the right side of the hypogas...
