Job descriptions:
Position 1: Improvement of hail detection and nowcasting by synergetic combination of information from polarimetric radar, model predictions and in-situ observations
Hail, the occurrence of which can be easily spotted especially in polarimetric radar observations, is a quite frequent phenomenon especially in summertime convective events. The identification especially of large hail, which is considered dangerous and potentially damaging, and its distinction from smaller hail is crucial for warnings but still difficult achieve. The hydrometeor classification scheme Hymec of DWD currently only discriminates one hail class besides hail together with rain. An experimental (Hail Size Discrimination Algorithm HSDA for S band based on polarimetry by Ryzhkov et al. (2013) and Ortega et al. (2013) distinguishes between small (ᴓ < 2.5 cm), large (2.5 cm < ᴓ < 5.0 cm), and giant hail (ᴓ > 5.0 cm). The prime goal of this project is the extension of Hymec by adapting the HSDA methodology to C-band and by exploiting its even larger potential at this wavelength for hail detection. In addition, the potential of the Circular Depolarization Ratio (CDR), which might be detectable also from DWDs C-Band radars will be exploited in addition to differential polarization (ZDR) for nowcasting of hail events. To better understand the hail and hail size signatures and its precursors above the melting layer, we will also use the overlapping observations of the Bonn and Jülich X-band radars for independent remote sensing information. Observations of hail occurrence and size for algorithm tuning and evaluation will be taken from DWDs and our own disdrometer network and from the growing European Severe Weather Database (ESWD) from ESSL.
Position 2: Improvement of nowcasting for winter precipitation by synergetic combining information from polarimetric radar, model predictions and in-situ observations
It is extremely important to know the precise location of rain/snow boundary at the surface and its progression in time, and also to know where and when e.g. freezing rain changes to ice pellets or vise versa. The project will derive an improved methodology to delineate this boundary and its progression in near future based on a synergetic use of dual-polarization observations of the DWD radar network, in-situ surface observations from meteorological stations, disdrometers and radiosondes, NWP fields, and a 1D bin microphysical model. The Hymec hydrometeor typing scheme will be evaluated in a first step for winter precipitation cases. In a second step the project will – based on the evaluation results and an extended use of polarimetric observations including the underutilized variable circular depolarization ratio CDR - try to improve on the estimators for precipitation type, phase and intensity. The third step will further improve Hymec by using current radiosonde observations and NWP model predictions by involving a 1D bin microphysics model, which predicts ensembles of physically consistent hydrometeor profiles including their polarimetric moments. The comparison between the ensemble and the polarimetric observations will be used to derive a probabilistic hydrometeor analysis. The fourth step will aim at nowcasting the precipitation field by advection methods and exploiting the uncertainty involved in the phase and the advection vectors for an ensemble approach. The fifth step will use the in-system tendencies of polarimetric fingerprints in the precipitation generating layers and NWP predictions of the thermodynamic state to include system evolution including uncertainty in the nowcasting.

PHD CANDIDATE (PROMOVENDUS) CHANGING CLIMATIC EXTREMES IMPACTING NATURAL HAZARDS
The department Earth System Analysis of the University Twente and KNMI have a vacancy for a joint PhD position. The department of Earth Systems Analysis (ESA) combines earth science knowledge with spatial modelling and advanced remote sensing to understand earth processes in space and time. Our education and research contribute to a sustainable use of energy and earth resources, and help reduce disaster risk and the impact of natural hazards on society. We have a strong track record in research and capacity development projects all over the world, with emphasis on East Africa, South East Asia and the Central America/Caribbean.
The research group Natural Hazards and Disaster Risk management is part of the department ESA. Our research focuses primarily on natural and man-made hazards and on disaster risk management, using relevant geo-information.
KNMI is the national institute for weather, climate, and seismology in the Netherlands.
JOB DESCRIPTION
Climatic extremes are a major trigger for many natural hazards and disasters, such as flooding, drought, and land slides that cause loss of life or property damage. Understanding of climate change is crucial for proper future hazard risk assessment. It is a challenge to incorporate non-stationary behavior of climate change in disaster risk assessment, where other actors, such as change in population growth, land-use, spatial planning, play an important role too. Exploring new ways to translate climate data into information for disaster risk reduction is a creative challenge where multiple fields meet.
The research will focus on optimizing use of climate data for hydro-meteorological hazard assessment. You will work on the development of a statistical toolbox, where non-stationary relationships between climatic extremes, climate change, and hydro-meteorological hazards will be combined. Advancing knowledge on the atmospheric conditions linking to hazardous conditions is a primarily goal of this research, using multiple data sources: e.g. in situ meteorological observations, atmospheric remote sensing data, local and regional hazard inventories and climate model data. One example is establishing the link between dominant atmospheric circulation patterns and reoccurrence of floods or landslides. The methods developed will be tested for data rich areas (such as the Netherlands) and applied to data sparse regions (typically countries in transition). The research will be highly multi-disciplinary. You will work on a 50/50 basis at both institutes, to optimize utilization of available data and knowledge at University of Twente and KNMI.
YOUR PROFILE
We are searching for an enthusiastic, creative and perseverant candidate with the following qualifications:
An MSc in physics, mathematics, atmospheric sciences, physical geography or a related discipline
Experience with statistical analyses techniques is desirable

PHD CANDIDATE (PROMOVENDUS) LAND USE CHANGES IMPACT ON METEOROLOGICAL TRIGGERS FOR FLOODS
The department of Earth Systems Analysis (ESA) combines earth science knowledge with spatial modelling and advanced remote sensing to understand earth processes in space and time. Our education and research contribute to a sustainable use of energy and earth resources, and help reduce disaster risk and the impact of natural hazards on society. We have a strong track record in research and capacity development projects all over the world, with emphasis on East Africa, South East Asia and the Central America/Caribbean.
The research group Natural Hazards and Disaster Risk management is part of the department ESA. Our research focuses primarily on natural and man-made hazards and on disaster risk management, using relevant geo-information.
JOB DESCRIPTION
Meteo-hydrological hazards could change in probability and intensity due to global climate change, but also due to local land use changes. The mutual feedback mechanisms between land use changes and atmospheric changes are of major interest for flood hazard assessment as they enhance or decrease the hazard risk. Of particular interest is how changes in land surface processes, e.g. due to urbanization, impacts the frequency and magnitude of extreme weather events triggering flooding. The candidate will contribute to research leading to impact assessment of spatial planning and global climate change on the local climatology, and its impact on flood hazard risk of cities. The focus will be mainly on cities located in lesser developed countries.
You will work on the complex relationship between changes in spatial planning and the local climatology, focusing on the impact on flood hazard risk. State-of-the-art atmospheric and hydrological models will be utilized to assess the contribution of land use and land cover changes on the local atmospheric conditions and related water balance. To analyze the impact of changes, historical meteorological and hydrological data information will be evaluated where such data is well available, complemented with satellite image datasets.
YOUR PROFILE
We are searching for an enthusiastic, creative and perseverant candidate that has/is:
An MSc in Meteorology, Hydrology, Physical Geography or related subject
Prior exposure to or knowledge in atmospheric and/or hydrological modelling. Hydro-meteorological remote sensing would be beneficial as well
Familiar with computer programming
Excellent written and spoken English language skills
Good communication skills
Information and application
