Soil-atmosphere relationships: The Hungarianperspective

Abstract

This study discusses scientific contributions analyzing soil-atmosphere relationships. These studies deal with both the biogeophysical and biogeochemical aspects of this relationship, with biogeophysical aspects being in the majority. All of the studies refer either directly or indirectly to the fundamental importance of soil moisture content. Moisture has a basic influence on the spatiotemporal pattern of evapotranspiration, and so 1) on cloud formation and precipitation events by regulating the intensity of convection, and 2) on the trace-gas exchanges in the near-surface atmosphere. Hungarian modeling efforts have highlighted that soils in the Pannonian Basin have region-specific features. Consequently, shallow and deep convection processes are also, to some extent, region-specific, at least in terms of the diurnal change of the planetary boundary layer height and the spatial distribution of convective precipitation. The soil-dependent region-distinctiveness of these two phenomena has been recognized; at the same time the strength of the relationships has not yet been quantified.

The Importance of Soil‐Type Contrast in Modulating August Precipitation Distribution Near the Edwards Plateau and Balcones Escarpment in Texas

“…The impact of soil hydraulic parameters on precipitation has been investigated previously, mostly in Hungary (Acs et al, 2010;Acs et al, 2015;Horvath et al, 2009) and in China (He et al, 2016). Most of these previous investigations demonstrated certain sensitivities of precipitation to some soil hydraulic parameters; in particular, He et al (2016) reported a large sensitivity of WRF-simulated precipitation to wilting point soil moisture contents.…”

Computation of daily Penman–Monteith reference evapotranspiration in the Carpathian Region and comparison with Thornthwaite estimates

“…This was the first step to-wards creating a realistic daily evaporation database, which is one of the tasks specified in the Science and Implementation plan of the PannEx project (Lakatos et al, 2018). For this purpose, more detailed soil and surface cover databases should be built and reliable soil moisture data (measured or calculated) will be needed (Breuer et al, 2012;Ács et al, 2015). The estimation of the components of the radiation balance will be followed by the parametrization of turbulent fluxes.…”

Human thermal climate of the Carpathian Basin

“…According to the results obtained, the human thermal load in the Pannonian Plain part of the Carpathian Basin (Ács et al ., 2015) during summer is approximately equal regardless of the personal differences. However, in winter the relevance of personal differences upon human thermal load can be significant.…”

“…In this study, we will focus on the Carpathian Basin because of its unique ecological and climate features (Metzger et al ., 2005; Borhidi et al ., 2013; Ács et al ., 2015). Its climate is mostly investigated by means of vegetation based methods (e.g., Réthly, 1933; Ács and Breuer, 2013; Szelepcsényi et al ., 2014).…”
