Of similar significance are his investigations of transient forms of reconnection in form of flux-transfer events, of the nature and structure of magnetopause and boundary layers in dependence of the orientation of the interplanetary magnetic field, and the understanding of the thermalization process in supercritical quasi-perpendicular collisionless shocks.

He is recognised as world-wide expert on high atmosphere chemistry of meteors and metals and made several discoveries in metals in the mesosphere. Plane recently explained the anomalous behavior of potassium, a 50-years unresolved problem. He also made some unique measurements of NO3, BrO, IO, OIO in the marine boundary layer, and made several discoveries in halogen radicals in the atmosphere.

Projected sea level change in Venice in the context of historical observations. Observations are annual-mean tide gauge relative sea-level (RSL) height anomalies with respect to the 2000-2007 average.

“Strong actions and further effective legislation are essential to avoid the drastic deterioration of air quality, which can have severe effects on human health,” concludes the team of scientists, led by Andrea Pozzer of the Abdus Salam International Centre for Theoretical Physics in Italy (now at the Max Planck Institute of Chemistry in Germany), in the new paper.

Harrison’s measurement techniques have been widely disseminated, with 34 papers in the well-established American Institute of Physics’ journal Review of Scientific Instruments alone. His highly useful graduate-level textbook on “Meteorological Measurements and Instrumentation”, describing the physical principles and technological ingenuity of various measurements, provides an essential account of the history of atmospheric measurements in the context of modern climate science and of the future of observational meteorology in terms of emerging sensors and technologies.

Aside from many other seminal papers, Katy also played an important organizational role in the Nonlinear Geosciences community. She was one of the first chairs of EGSs Nonlinear Processes (NP) section and the key organizer of a remarkably interdisciplinary, week-long meeting in Crete, in the summer of 1985. The resulting proceedings, “Irreversible Phenomena and Dynamical Systems Analysis in the Geosciences,” edited by C.

He also explored the domain of risk assessment, investigating the impacts of landslides and floods in terms of losses. He was positioned on the list of the best scientists (0.27th percentile) in all scientific disciplines for 2018.

She showed that turbulent flows can sustain dynamos and found the saturation mechanism. In particular, she pioneered studies of the role of helicity in geophysical and astrophysical flows. She predicted the existence of an inverse cascade of magnetic helicity in conducting fluids and formulated the concept of ‘selective decay’, meaning that the magnetic helicity decays slower than energy.

In some of the earliest model realisations used for assessments, Prather developed a simple method for the accurate determination of the atmospheric lifetimes of many ozone-depleting and greenhouse gases that remain in use today. In the climate-change arena, he pioneered the use of a mathematical formalism to deconstruct chemical interactions in the atmosphere.
