The decadal abrupt change in the global land vapor pressure deficit
نویسندگان
چکیده
The vapor pressure deficit (VPD) is an important variable used to characterize atmospheric aridity. This paper analyses the spatial and temporal characteristics of decadal abrupt change (DAC) in global land VPD after 1980 using monthly scale data from Climatic Research Unit. results show that 60.5% area underwent a significantly increased (IDAC) VPD, persistent IDAC was obvious middle low latitudes Eurasia, Africa parts South America but not central North or Western Siberia. From 2020, most regions experienced no more than two IDACs, while significant increases occurred mainly around Mediterranean eastern America. relatively early Africa, 2000 high latitude regions, Eastern Europe, near Qinghai-Tibet Plateau. where lasted longer 10 years included West Asia, America, East indicating aridity these were obvious. In general, began 1993–2000 other periods before 1990, suggesting experiencing increase has expansion 1990s role water limitation this Central Asia China strengthened. addition, showed another large-scale over region 2009, intensified last decade. At same time, few exhibited decreased changes (DDACs) with durations shorter 2 years.

Historical changes of temperature and vapor pressure deficit during the crop growing season in Iran
Climate change variables have rarely been analyzed specifically for the growing season of crops. In this study, changes in minimum (Tmin) and maximum temperature (Tmax), daily maximum saturated vapor pressure (VPsat) and estimated daily VPD weighted for transpiration (VPDtran) were examined at five locations in Iran over 40 years during the growing seasons of chickpea and maize. The results of ...

Stomatal responses to changes in vapor pressure deficit (VPD) constitute the predominant form of daytime gas-exchange regulation in plants. Stomatal closure in response to increased VPD is driven by the rapid up-regulation of foliar abscisic acid (ABA) biosynthesis and ABA levels in angiosperms; however, very little is known about the physiological trigger for this increase in ABA biosynthesis ...
