Abstract Since the pioneering paper by Nastrom and Gage on aircraft-derived power spectra, significant progress has been made in understanding the wavenumber distribution of energy in Earth’s atmosphere and its implications for the intrinsic limits of weather forecasting. Improvements in tropical cyclone intensity predictions have lagged those of global weather forecasting, and limited intrinsic predictability may be partially responsible. In this study, we construct power spectra from aircraft data of over 1200 missions carried out by the National Oceanic and Atmospheric Administration (NOAA) and Air Force Reserve Command (AFRC) Hurricane Hunters. Each mission is parsed into distinct flight legs, and legs meeting a specified set of criteria are used for spectral analysis. Here, we produce power spectra composites for each category of the Saffir–Simpson scale, revealing a systematic relationship between spectral slope and storm intensity. Specifically, as storm intensity increases, we find that 1) spectral slope becomes steeper across scales from 10 to 160 km and 2) the transition zone where spectral slope begins to steepen shifts downscale.

Hereditary Factors

Motion Sickness surveys were administered to 77 male graduate students and 95 male and female members of an Air Force Reserve medical unit. Results of Survey 1 indicated significant and sizeable correlations between sons and their natural fathers for severity of motion sickness symptoms of fatigue, headache, and nausea. Stepwise multiple regression indicated that the father's nausea accounted for 59.4% of the total variance of their son's nausea during travel. Results of Survey 2 indicated sizeable and significant correlations between respondents and both natural parents for percentage of reported symptoms of fatigue and headache. Stepwise multiple regression indicated that both parents' reported percentage of fatigue (26.6%) and headache (33.6%) reliably predicted the respondents' percentage of fatigue and headache symptoms but not the nausea symptoms. In addition, there were no significant correlations between self-reported symptoms of fatigue, headache, and nausea. Findings suggest (1) hereditary factors may be a significant contributor to motion sickness, both in severity and frequency of symptoms, and (2) fatigue, headache, and nausea are largely independent of each other. Indications are that motion sickness be considered a syndrome rather than a unitary disorder.
