Application of Year of Polar Prediction- Southern Hemisphere (YOPP-SH) Observations for Improvement of Antarctic Numerical Weather Prediction

这项研究将利用作为世界气象组织“极地预测年”的一部分而收集的大量南极天气观测资料。研究人员将利用这些额外的观测结果来研究将数据纳入现有天气预测模型的新方法。这项研究的主要目标是提高南极洲天气预报的准确性。这项工作很重要，因为南极洲的恶劣天气极大地影响了科学研究和对这项研究的支持。能够准确地预测天气变化，提高了南极实地科学和作业的安全性和效率。 拟议的努力旨在推进世界气象组织极地预测项目及其南半球极地预测年（YOPP-SH）工作的目标。研究人员将调查和演示从YOPP-SH的特殊观测期获得的增强大气观测对极地数值天气预报的影响。这将通过使用南极中尺度预报系统进行。AMPS是美国南极计划（USAP）的主要数值天气预报能力。建模实验将评估特别观测期数据对南极预报的影响，并将作为测试AMPS新数据同化方法的工具。这项工作的主要目标是改进预报和数值天气预报工具。其成果将包括量化增强的南半球大气观测的价值。这项工作还将有助于提高AMPS及其支持USAP的能力。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This research will take advantage of the greater number of Antarctic weather observations collected as part of the World Meteorological Organization's "Year of Polar Prediction". Researchers will use these additional observations to study new ways of incorporating data into existing weather prediction models. The primary goal of this research is to improve the accuracy of weather forecasts in Antarctica. This work is important, as the harsh weather in Antarctica greatly impacts scientific research and the support of this research. Being able to accurately predict changing weather increases the safety and efficiency of Antarctic field science and operations. The proposed effort seeks to advance goals of the World Meteorological Organization's Polar Prediction Project and its Year of Polar Prediction-Southern Hemisphere (YOPP-SH) effort. Researchers will investigate and demonstrate the forecast impact of enhanced atmospheric observations obtained from YOPP-SH's Special Observing Period on polar numerical weather prediction. This will be done by using the Antarctic Mesoscale Prediction System (AMPS). AMPS is the primary numerical weather prediction capability for the United States Antarctic Program (USAP). Modeling experimentation will assess the impact of Special Observing Period data on Antarctic forecasts and will serve as a vehicle for testing new data assimilation approaches for AMPS. The primary goal for this work is improved forecasting and numerical weather prediction tools. Outcomes will include quantification of the value of enhanced southern hemisphere atmospheric observations. This work will also help improve AMPS and its ability to support the USAP.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
