Spatiotemporal Characteristics and Synoptic Patterns of Dry‐Hot Winds (Sukhoviys) in Ukraine

International Journal of Climatology, EarlyView.
This study analyses dry‐hot winds, or sukhoviys, a recurrent phenomenon during the warm season across Ukraine that contributes to rapid moisture loss from soil and vegetation. The activity of sukhoviy events was assessed using the introduced Sukhoviy Station Index, accounting for their meteorological characteristics and frequency of occurrence.

The study of the ratio of actual evapotranspiration and potential one to estimate the actual evapotranspiration for a year using the vegetation distribution

PROCEEDINGS OF HYDRAULIC ENGINEERING, 1999
In order to grasp the process of hydrologic cycle in river basin, it is necessary to estimate the evapotranspiration correctly. But, it is difficult to observe the meteorological data for the evapotranspiration, because of the extent of observation area.

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

International Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

A composite method for estimating annual actual evapotranspiration [PDF]

Hydrological Sciences Journal, 1988
Abstract There are two ways which can be used to estimate annual actual evapotranspiration, one being an indirect estimation method using the water balance of a catchment, the other being the use of evaporation pan data or climatic data. The method in this paper belongs to the second type.

Remote sensing estimation on regional continuous daily evapotranspiration based on Richards equation

Shuiwen dizhi gongcheng dizhi
Evapotranspiration (ET) is an important part of water cycle in nature, and the estimation of evapotranspiration on spatio-temporal scale has always been a hot issue. Remote sensing can estimate evapotranspiration on regional scale, but it is difficult to

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

An analysis of actual evapotranspiration

The main interacting factors determining the actual evapotranspiration from crops were analysed.The apparent diffusion resistance of the crop was introduced because of the geometry of the evaporative surface. Its relation to light intensity and to suction in the leaves had been estimated for grass.The precipitation intercepted by the crop increased ...

Estimation of Evapotranspiration ETc and Crop Coefficient Kc of Wheat, in south Nile Delta of Egypt Using integrated FAO-56 approach and remote sensing data

Egyptian Journal of Remote Sensing and Space Sciences, 2012
Crop water requirements are represented by the actual crop evapotranspiration. Estimation of crop evapotranspiration (ETc) and crop coefficient using remote-sensing data is essential for planning the irrigation water use in arid and semiarid regions ...
