Spectral window of systolic blood pressure showing biggest amplitude (arrow) near period of Richardson's variation in solar wind speed. Data of 72-year old man at the start of the 5-year record of mostly 30-minute automatic "ambulatory" measurements with an A&D monitor (except for an about 2-month break). Uncertainty regions serve only for ordering. A trans-year is prominent and can be resolved in addition to an about-yearly component in human blood pressure [8, 171], as anticipated from the role of biospheric-environmental spectral reciprocity [56]. The presence of a trans-year was confirmed in each of the available human blood pressure and heart rate series covering over 5 (up to 36) years.
