The influence of wind and turbulence on urban bat and insect activity

Airborne animals such as flying insects or bats are exposed to wind that can influence their activity given the associated high-energy costs with high wind speeds and strong turbulence. Some studies investigating the relation between bat activity and wind. However, atmospheric motion has also other characteristics such as turbulent kinetic energy and friction velocity that has been so far overlooked in relation to bats. Given that buildings and tall trees will also have an impact on wind and turbulence besides temperature and humidity this knowledge is crucial to get an understanding about how bat species will be able to deal with atmospheric condition in cities. The aim of this Master thesis is to get an understanding about the effect of wind and turbulences on bat and flying insect (bat prey items) activity and occurrence. The thesis will start mid August 2021 and involve fieldwork (i.e. recording bat calls and catching insects), analyzing bat calls and identifying insects to order level. Atmospheric variables such as wind speed, wind direction, three-dimensional flow characteristics, turbulence, temperature and humidity will be measured at different heights at the 40 m tower of the Urban Climate Observatory Berlin. Analyses will be undertaken in R. The location of study is the garden of the Institute of Ecology, Rothenburgstraße 12, Berlin.
We are looking for an engaged student who would like to investigate this further in a master thesis.

Characterization of Weather Conditions during Heat Waves in Berlin - Model Data

Although there is currently no uniform definition of heat waves worldwide, heat waves can be described quite generally as episodes of increased air temperature. However, other meteorological variables such as humidity, wind, cloud cover, and radiation fluxes can also deviate significantly from "normal" conditions during heat waves. In particular, precipitation prior to a heat wave can also be of critical importance in determining how a heat wave manifests itself (intensity, length). Furthermore, heat waves can differ from each other, depending on the prevailing meteorological conditions. The purpose of this paper is to characterize the meteorological/climatological conditions of the atmosphere during heat waves in comparison to "normal" climatic conditions. The investigation shall refer to the Berlin-Brandenburg area, where heat waves currently occur several times per year. Data basis of this work shall be a gridded atmospheric dataset with a spatial resolution of up to 2 km grid resolution for the years 2001-2016, created by dynamic downscaling. In addition, meteorological data from the German Weather Service as well as from the department's own measurement network UCON can be used.

The influence of the different radiation fluxes on the mean radiation temperature in SOLWEIG.

For the bioclimate of humans, the short-wave radiation of the sun as well as the thermal radiation of surfaces play a decisive role in the exterior during the day. These different radiation fluxes can be summarized with the variable "mean radiation temperature" (Tmrt). This variable can be determined experimentally by means of different measurement methods, as well as calculated on the computer with the help of radiation models. One of these models is the micro-scale SOLWEIG model (SOlar and LongWave Environmental Irradiance Geometry model), which is frequently used in science for questions concerning urban areas. Studies have shown that the model is sensitive to the input variables of solar radiation, especially with respect to the distinction between diffuse and direct radiation compared to global radiation as a combined variable. By means of various measured data, this sensitivity to Tmrt will be determined. Extensive radiation measurements for the model input from long-term measurements (global radiation, direct and diffuse short-wave radiation, long-wave atmospheric radiation), as well as data for the validation of the model results from a measurement campaign in summer are available for this purpose. Specifically, it will be examined how the different input quantities of radiation affect the model results for a Berlin courtyard structure.

Urban Climate Measurement Network TU Berlin - Homogenization and Spatiotemporal Investigation of Air Temperature

The department's own urban climate measurement network has been continuously collecting data on air temperature and humidity, among other things, since the early 1990s. During this time, there have been several changes regarding the measurement technique and the measurement intervals. Based on the long-term data, a bachelor's/master's thesis will investigate to what extent these changes could have led to inhomogeneities in the data. In a second step, the spatio-temporal patterns of air temperature within the city will be investigated. The urban development of Berlin, spatial differences between the measurement sites, site-specific differences in urban structural variables, meteorological conditions, and the regional climatic trend will play decisive roles.

Spatial and temporal variability of surface temperatures of urban vegetation.

Using thermal images, it is possible to determine the temperature of plant surfaces. Which factors influence the variability of this temperature? This question will be answered with the help of thermography and meteorological data.

Derivation of urban structural variables from digital terrain and surface models for urban climatological analyses.

The urban climate is strongly influenced by the building structure. Morphometric variables such as the ratio of building height to street width or the ratio of building surface area to floor area are important for urban climate analysis.

Orographic influence on precipitation variability in the central High Andes.

Precipitation in semi-arid areas of the Central High Andes plays a significant role in vegetation dynamics. This bachelor thesis will use available precipitation data and elevation model data to determine the influence of regional orography on precipitation in an example region in southern Peru.

Spatial distribution of High-Andean wetlands

High Andean wetlands (HW) are located in the cold and arid high mountain steppes of Peru, Chile, Bolivia, as well as Argentina, and assert themselves at the hygrothermal growth limit, serving as refugia for numerous wildlife species and as grazing grounds for alpaca and llama herds of the High Andean population. Literature studies and remote sensing data will be used to determine the spatial distribution of HW throughout the Andean region.
