The challenges of extreme droughts require the adaptation of agriculture especially during the intense growth phase of crops. For dryland farming, the selections of the optimal land use type and sustainable agricultural land management are potential adaptation tools for facing the challenges posed by increased aridity. To this end, it is indispensable to understand soil moisture (SM) dynamics under different land use types over drought-affected periods. Within the framework of a Slovenian–Hungarian project, soil moisture, matric potential and rainfall time series have been collected at three pilot sites of different land use types (pasture, orchards and a ploughland) in SW Hungary since September 2018. Experiments were carried out in soils of silt, silt loam and clay loam texture. In the summers (June 1 to August 31) of 2019 and 2022, we identified normal and dry conditions, respectively, with regard to differences in water balance. Our results demonstrated that soil moisture is closely controlled by land use. Marked differences of the moisture regime were revealed among the three land use types based on statistical analyses. Soils under pasture had the most balanced regime, whereas ploughland soils indicated the highest amplitude of moisture dynamics. The orchard, however, showed responses to weather conditions in sharp contrast with the other two sites. Our results are applicable for loamy soils under humid and subhumid temperate climates and for periods of extreme droughts, a condition which is expected to be the norm for the future.}, year = {2023}, eissn = {2071-1050}, orcid-numbers = {Czigány, Szabolcs/0000-0002-9158-3162; Sarkadi, Noémi/0000-0002-2370-8621; Lóczy, Dénes/0000-0002-2542-6775; Fábián, Szabolcs Ákos/0000-0001-9127-2113; Ciglič, R/0000-0003-3517-3780; Ferk, M/0000-0003-0145-7590; Pirisi, Gábor/0000-0003-0179-3228; Imre, Marcell/0009-0002-2785-2521; Nagy, Gábor/0000-0003-1755-9719; Pirkhoffer, Ervin/0000-0003-2917-3290} } @CONFERENCE{MTMT:34392603, title = {Application of the Piggybacking Methodology to Real Convective Cases}, url = {https://m2.mtmt.hu/api/publication/34392603}, author = {Sarkadi, Noémi and Geresdi, István and Lulin, Xue and Wojciech, W. Grabowski}, booktitle = {103rd Annual Meeting of the American Meteorological Society}, unique-id = {34392603}, abstract = {In a chaotic system, like moist convection, it is difficult to separate the impact of a physical process from effects of natural variability. This is because modifying even a small element of the system physics typically leads to a different system evolution, and it is difficult to tell whether the difference comes from the physical impact or it merely represents a different flow realization. Piggybacking is a relatively simple and computationally efficient modelling methodology that allows separation of the two. The idea is to use two sets of thermodynamic variables (the temperature, water vapor, and all aerosol, cloud, and precipitation variables) in a single cloud simulation. The two sets differ in a specific element of the physics, such as aerosol properties, microphysics parameterization, large-scale forcing, environmental profiles, etc. One thermodynamic set is coupled to the dynamics and drives the simulated flow, and the other set piggybacks the flow, that is, thermodynamic variables are carried by the flow but they do not affect it. We have recently implemented the piggybacking methodology in Weather Research and Forecasting (WRF) model to study the impact of selected physical processes on the cloud dynamics and microphysics in simulations of convective cases (Sarkadi et al. 2022). This presentation will discuss results from the initial set of simulations applying bulk microphysical parameterizations targeting selected cases from the Convective Precipitation Experiment (COPE) over the south-western UK. COPE convective clouds were well observed, and data are available to compare the observed and simulated microphysical and dynamical characteristics of these clouds. The simulations explore impacts of (i) aerosol loading; (ii) secondary ice production (the Hallett-Mossop process) and (iii) terminal velocity of hydrometeors. Sarkadi, N., L. Xue, W. W.

This cloud was well observed during the Small Cumulus Microphysics Study field campaign (Lasher-Trapp et al. 2005) that took place in 1995 in Florida (USA). The UPNB scheme is modified to simulate the seeding effect by adding a new category for the water drops containing seeding materials. The size distribution of the seeding material is divided into 36 bins, so the size dependence of the seeding effect is taken into consideration. Because the mass of embedded hygroscopic aerosol particles inside of the water drops is tracked for every mass bin, the formation of the regenerated hygroscopic particles due to the evaporation of the water drops is simulated as well. Implementing this bin scheme into the WRF numbers of numerical experiments are planned to perform. Sensitivity of the seeding efficiency on the size distribution, on the hygroscopicity, and on the total amount of the seeding materials seeding are planned to study. The efficiency of the seeding is evaluated by calculated the ratio the accumulated surface precipitation in the seeded and unseeded cases.}, year = {2022}, pages = {1}, orcid-numbers = {Sarkadi, Noémi/0000-0002-2370-8621} } @article{MTMT:33202808, title = {Generation of a flood susceptibility map of evenly weighted conditioning factors for Hungary}, url = {https://m2.mtmt.hu/api/publication/33202808}, author = {Sarkadi, Noémi and Pirkhoffer, Ervin and Lóczy, Dénes and Balatonyi, László and Geresdi, István and Fábián, Szabolcs Ákos and Varga, Gábor and Balogh, Richárd and Gradwohl-Valkay, Alexandra Ilona and Halmai, Ákos and Czigány, Szabolcs}, doi = {10.5937/gp26-38969}, journal-iso = {GEOGRAPHICA PANNONICA}, journal = {GEOGRAPHICA PANNONICA}, volume = {26}, unique-id = {33202808}, issn = {0354-8724}, abstract = {Over the past decades, in the mountainous, hilly and/or urban areas of Hungary several high-intensity storms were followed by severe flash flooding and other hydrologic consequences. The overall aim of this paper was to upgrade the national flash flood susceptibility map of Hungary first published by Czigány et al. (2011). One elementary watershed level (FFSIws) and three settlement level flash flood susceptibility maps (FFSIs) were constructed using 13 environmental factors that influence flash flood generation. FFSI maps were verified by 2,677 documented flash flood events. In total, 5,458 watersheds were delineated. Almost exactly 10% of all delineated watersheds were included into the category of extreme susceptibility. While the number of the mean-based FFSIs demonstrated a normal quasi-Gaussian distribution with very low percentages in the quintile of low and extreme categories, the maximum-based FFSIs overemphasized the proportion of settlements of high and extreme susceptibility. These two categories combined accounted for more than 50% of all settlements. The highest accuracy at 59.02% for class 5 (highest susceptibility) was found for the majority based FFSIs. The current map has been improved compared to the former one in terms of (i) a higher number of conditional factors considered, (ii) higher resolution, (iii) being settlement-based and (iv) a higher number of events used for verification.}, year = {2022}, eissn = {1820-7138}, pages = {200-214}, orcid-numbers = {Sarkadi, Noémi/0000-0002-2370-8621; Pirkhoffer, Ervin/0000-0003-2917-3290; Lóczy, Dénes/0000-0002-2542-6775; Balatonyi, László/0000-0001-5130-730X; Geresdi, István/0000-0002-3160-7900; Fábián, Szabolcs Ákos/0000-0001-9127-2113; Halmai, Ákos/0000-0001-5722-8119; Czigány, Szabolcs/0000-0002-9158-3162} } @article{MTMT:33043050, title = {Microphysical piggybacking in the Weather Research and Forecasting Model}, url = {https://m2.mtmt.hu/api/publication/33043050}, author = {Sarkadi, Noémi and Xue, Lulin and Grabowski, Wojciech W. and Lebo, Zachary J. and Morrison, Hugh and White, Bethan and Fan, Jiwen and Dudhia, Jimy and Geresdi, István}, doi = {10.1029/2021MS002890}, journal-iso = {J ADV MODEL EARTH SY}, journal = {JOURNAL OF ADVANCES IN MODELING EARTH SYSTEMS}, volume = {14}, unique-id = {33043050}, year = {2022}, eissn = {1942-2466}, orcid-numbers = {Sarkadi, Noémi/0000-0002-2370-8621; Xue, Lulin/0000-0002-5501-9134; Grabowski, Wojciech W./0000-0001-8480-9787; Lebo, Zachary J./0000-0002-1064-4833; Morrison, Hugh/0000-0002-3160-7900; White, Bethan/0000-0002-3467-7154; Dudhia, Jimy/0000-0002-2394-6232; Geresdi, István/0000-0002-3160-7900} } @article{MTMT:33118510, title = {Trends in extreme precipitation events (SW Hungary) based on a high-density monitoring network}, url = {https://m2.mtmt.hu/api/publication/33118510}, author = {Schmeller, Gabriella and Nagy, Gábor and Sarkadi, Noémi and Cséplő, Anikó and Pirkhoffer, Ervin and Geresdi, István and Balogh, Richárd and Ronczyk, Levente and Czigány, Szabolcs}, doi = {10.15201/hungeobull.71.3.2}, journal-iso = {HUNG GEOGR BULL (2009-)}, journal = {HUNGARIAN GEOGRAPHICAL BULLETIN (2009-)}, volume = {71}, unique-id = {33118510}, issn = {2064-5031}, abstract = {Climate change is commonly associated with extreme weather phenomena. Extreme weather patterns may bring prolonged drought periods, more intense runoff and increased severity of floods. Rainfall distribution is extremely erratic both in space and time, particularly in areas of rugged topography and heterogeneous land use. Therefore, locating major rainfall events and predicting their hydrological consequences is challenging. Hence, our study aimed at exploring the spatial and temporal patterns of daily rainfall totals of R ≥ 20 mm, R ≥ 30 mm and R ≥ 40 mm (extreme precipitation events, EPE) in Pécs (SW Hungary) by a hydrometeorological network (PHN) of 10 weather stations and the gridded database of the Hungarian Meteorological Service (OMSZ). Our results revealed that (a) OMSZ datasets indicated increasing frequencies of EPEs for the period of 1971–2020 in Pécs, (b) the OMSZ dataset generally underestimated EPE frequencies, particularly for R ≥ 40 mm EPEs, for the period of 2013 to 2020, and (c) PHN indicated a slight orographic effect, demonstrating spatial differences of EPEs between the two datasets both annually and seasonally for 2013–2020. Our results pointed out the adequacy of interpolated datasets for mesoscale detection of EPE distribution. However, topographically representative monitoring networks provide more detailed microscale data for the hydrological management of urban areas.

The RSD is often simply hypothesized to parameterize rain microphysics, which needs further modification to demonstrate the variability of the RSD. An idealized squall line case from MC3E (Midlatitude Continental Convective Clouds) field campaign on May 20th, 2011 is simulated to evaluate the effects of the modification of RSD in a bulk microphysics scheme. The RSD is modified using a diagnosed relation based on large samples of observations from Chongqing, China. A piggybacking framework in WRF is used to separate the microphysics and dynamics from their interactions. The simulations show that both microphysics and dynamics are important to the evolution and structure of the squall line. The microphysics of the RSD modification leads to stronger convective rain rate, less total rain amount, weaker low-level radar reflectivity and higher liquid water path. While the RSD-modified dynamics leads to faster system moving speed, increased total rain amount, decreased radar reflectivity in the low-level of convections. These changes are related to the fact that the modified RSD can change the mass- and number-weighted terminal velocity (V­q and Vn) and evaporation rate of raindrops. The changes of V­q and Vn result in the changes of mass loading and mean size of raindrops and its vertical distribution that contributes to the radar reflectivity. As a result, the modified RSD microphysics generates stronger negative buoyancy and therefore the intensified cold pool, which is important to the evolution of dynamics and thus the system moving speed. The RSD modification in this study greatly impacts the simulation of an idealized squall line.
