Abstract. Irrigation is a method of land management that can affect the local climate. Recent literature shows it affects mostly near-surface variables and associated with an irrigation cooling effect. However, there no common parameterization also accounts for realistic water amount, this factor could ascribe one cause to different impacts found in previous studies. This work aims introduce three new surface parameterizations within WRF-ARW model (v3.8.1) consider evaporative processes. The...

Recent studies using global climate models have suggested that irrigation, assuming unlimited water supply and all crops can be irrigated, may an option for regional cooling in southeast Australia. In this paper, idealised simulations, we aim to quantify the maximum possible benefits of irrigation Australia during a record breaking summer. By limiting amount applied actual used, only areas which are equipped it, our study provides much needed practical context on potential We conduct...

Irrigation is crucial for sustaining agriculture in certain regions; however, there are effects on the local climate. Previous studies discussed that irrigation signal might depend geographical region as well synoptic and climatic conditions. The work presented here aims to investigate mechanisms behind changes impact conditions depending changes. Different previous works, this employs convection-permitting simulations. processes parameterized three different ways evaporative loss. of focus...
Abstract. The Urban Heat Island (UHI) describes the increase of near surface temperatures within an urban area compared to its rural surrounding. While concept UHI is in itself quite simple, it more complex apply gridded datasets. main complication lies baseline definition. Therefore, we propose three approaches calculate spatial representation for datasets from (i) a single point baseline, (ii) averaged and (iii) nearest neighbor-based field. Based on these approaches, seven methods are...
The increase of temperature attributed to anthropogenic emissions is projected continue in future climate scenarios. Several protocols and policies are being put place several European countries reduce both impact human activities. Irish Reforestation policy a good example such protocols. Nevertheless often contemplated do not take into account their potential effects on the atmospheric variables. This study aims assess influence vegetation cover over Ireland, with respect surface livestock...

Irrigation plays a crucial role in maintaining an ideal soil moisture level for optimal crop development. This practice is nowadays indispensable farmers as method to adapt the challenges posed by climate change. The Earth science community has recognized additional effects of irrigation beyond its impact on and plant growth. Various studies have revealed that can influence atmospheric variables such 2-meter temperature, relative humidity, even precipitation. Furthermore, researchers...
The development of regional reanalyses aims at the provision high-resolution data sets that are suitable for climate applications and services. As desired information can barely be provided by either synoptic or remote sensing observation data, a growing interest in high-quality is recognisable. Particular demand arises from renewable energy sector. Further quality gains expected using an ensemble approach, e.g. making available uncertainty when moving towards higher resolution. Within...
Regional reanalysis data sets are becoming more used and requested for a broad spectrum of users, from climate adaptation mitigation, to agricultural economical applications (e.g. energy meteorology). While the development system mainly relies on an existing numerical weather prediction (NWP) model corresponding assimilation scheme, it involves large amount testing both computational technical perspective.The talk will present preliminary results new pan-European regional at Deutscher...
Irrigation is one agricultural practice that contributes to maintain an optimal soil water content for crop development. Currently, farmers find this as essential method adapting climate change. The Earth science community identified some irrigation effects beyond moisture and plant growth impact, multiple studies found influence on atmospheric variables such 2 m temperature, relative humidity even precipitation. Moreover, the effect of Earth’s system has been studied various...
Modelling studies in hydrology depend on a good representation of forcing data, particular precipitation, for process representation, especially at the catchment  or sub-catchment scale. Forcing data is often provided through reanalysis, that use observations to obtain model states with smallest possible errors and biases. Here, we present prototype convection-permitting reanalysis system using coupled atmosphere-land utilizing ICON-eCLM EURO-CORDEX domain resolution 3km. Due high...

<p>In recent years convection-permitting models are increasingly often used for retrospective climate studies. Besides the better reproduction of atmospheric processes, increase in resolution allows a more accurate representation land-surface heterogeneities and thus realistic depiction smaller scale characteristics.
