Assessing the skill of state-of-the-art seasonal climate prediction techniques over Ethiopia - Andualem Shiferaw
  • Dissertation Defense
  • 11/28/2023

Skillful, timely, and reliable seasonal forecasts are crucial in mitigating the adverse impacts of climate-induced risks in Ethiopia and the rest of Greater Horn of Africa region. However, access to skillful and usable forecasts is currently challenging. This study evaluated the skill of raw and bias-corrected deterministic and probabilistic summer (JJA) rainfall forecasts from the Climate Forecast System Version 2 (CFSv2) for Ethiopia, spanning lead times from 0.5 to 4.5 months. The investigation also considered the influence of increased ensemble size on forecast skill by comparing performance of CFSv2 with the North American Multi-Model Ensembles (NMME). The findings indicated that CFSv2 exhibited limited skill for operational use in seasonal rainfall forecasting over Ethiopia. In contrast, NMME displayed promise, suggesting that with some value addition efforts such as bias correction, statistical downscaling, and identification of smaller subset of best performing models, could position it as a valuable component in Ethiopia's seasonal climate forecast services.

Despite their potential usefulness, coarse resolution global models like CFSv2 fail to meet users’ need for forecasts at local to regional scales. To address this limitation, the Weather Research and Forecasting model (WRF) was explored for its potential to enhance CFSv2 forecasts through downscaling. A sensitivity study using WRF identified optimal parameterization schemes, utilizing Climate Forecast System Reanalysis (CFSR) for initial and boundary conditions. Subsequently, the WRF model, configured with the identified optimum model configuration, was employed to downscale operational CFSv2 summer season rainfall forecasts. Despite downscaling a small subset of ensemble members, the WRF model demonstrated value in refining raw CFSv2 forecasts. However, additional research is essential to further fine-tune WRF configurations, potentially minimizing biases and enhancing forecast skill. The findings of this study are expected to contribute towards improving access to skillful and usable seasonal predictions that could help decision-makers in mitigating adverse impacts of climate induced risks.

Monitoring and assessing forage production in grazed grasslands of Nebraska: Toward Adaptive Grazing - Biquan Zhao
  • Dissertation Defense
  • 11/06/2023
Grasslands are an important natural resource in Nebraska providing critical ecosystem services, for example, supporting the local cattle\beef production by forage production. To achieve the goal of developing adaptive grazing management strategies and operating adaptive grazing systems in Nebraska, it is necessary to understand the forage production patterns and dynamics. This presentation describes trends in forage production, responses of forage production to weather factors and management, and effects of forage condition on cattle grazing, through monitoring and assessing forage production on grazed grasslands in Nebraska. Quadrat-sampling data, drone-based remotely sensed data, and cattle GPS collar data are used in studies of this dissertation. Results of this dissertation are informative for shaping adaptive grazing management strategies in Nebraska, which provides knowledge and improves our understanding of forage production patterns in grazed grasslands in the face of climate change, various grassland management practices and grazing activities.
Localizing Climate Assessment Tools - Stonie Cooper
  • Dissertation Defense
  • 04/25/2023

Focus on global climate change can overlook the nuances of local weather and climate impacts. This study describes tools and methods for creating and observing weather and climatic conditions on a temporal and geographic scale that represents the environment of Nebraska. Recognition of the limited resources available for continuous application of new data and gathering of observations provides a guide for a “best practice” scientific, yet economic, model for maintaining an observational network and deriving value-added products.

Utilizing Federally maintained datasets of geographically relevant cooperative observations as a backdrop, the locally implemented and maintained weather observation network, the Nebraska Mesonet, is assessed against the official national climate records. Strategies for increasing the relevance and reliability of the Nebraska Mesonet observed parameters that show inconsistencies are discussed. Quality control techniques are tested and evaluated to provide confidence in the recorded observations, with recommendations made to mitigate and limit errant data from entering an official Nebraska Mesonet record.

Impacts of Irrigation on a Precipitation Event During GRAINEX in the High Plains Aquifer Region - Daniel Whitesel
  • Thesis Defense
  • 03/29/2022

Land use land cover change, including irrigation, impacts weather and climate. In this thesis a precipitation event that occurred during the Great Plains Irrigation Experiment (GRAINEX) is investigated. The event was observed on the morning of 23 July 2018. Six model-based experiments were conducted which involved increase or decrease of soil moisture by 5% and up to 15% over the irrigated croplands. These changes were approximation of soil moisture content in response to different levels of irrigation applications. An additional experiment, where irrigated land use was changed to grassland, was conducted to capture pre-irrigation land use and its impacts. It was found that regardless of level of irrigation, average precipitation decreased. However, precipitation decrease was greater under drier conditions. In addition, as observed, the model did not produce precipitation over non-irrigated land use. When grassland replaced the irrigated agriculture, increases in precipitation was reported. With increased irrigation, latent heat flux increased compared to control simulation and decreased when irrigation decreased. On the other hand, sensible heat flux was decreased compared to control when irrigation increased. The planetary boundary layer over irrigated land use was shallower than over non-irrigated land use while over grassland it was higher than irrigated but lower than non-irrigated land use. The changes in precipitation, the surface energy balance, and the planetary boundary layer served as a reminder of irrigation’s complex effects on the atmosphere. Additional analysis of the other precipitation events during GRAINEX would be helpful to better understand the effects of irrigation.
