An observational study of a circular gust front over the Yangtze Delta, China
Weather, EarlyView.Concentric gust fronts are formed when a thunderstorm's downdraft reaches the ground and the outflow from the cold pool spreads uniformly outwards into the surrounding warm and humid air mass. Observational evidence presented here show the case of narrow‐band echoes forming a ring around a thunderstorm.

, 1997 A new solution for the static geopotential, TEG-3, complete to 70×70 in spherical harmonics, has been obtained. The solution represents one of the latest efforts to improve the Earth’s gravity model. The solution was obtained by combining inhomogeneous satellite and in situ data sets, and by simultaneously estimating the relative weights for individual

The Bayesian sinking in Porticello: a predictable convective windstorm?
Weather, EarlyView.The meteorological phenomenon that led to the Bayesian yacht sinking in Sicily at 0206 utc on 19 August 2024 is here investigated. A thunderstorm occurred during the sinking, but uncertainties exist regarding whether a waterspout or a downburst affected the ship. An in‐depth analysis of available observations highlighted that the ship was likely struck

The exterior tidal potential acting on a satellite [PDF]
A theory is presented that points out the existence of several long period and 'cross effects' in the coefficients in the expansion of the geopotential and in the motion of satellites.

Geopotential and geodynamic meters
Eos, Transactions American Geophysical Union, 1930 The work done in lifting a mass m, h units of length vertically, is given by the equationw = m g hprovided g, the local gravity‐acceleration, is constant over the distance in question. If g varies with height, and we know it does, then we must resort to integration and writew = m ∫ohg dhand express g as a function of h.

Journal of Ecology, EarlyView.This work demonstrates the control of teleconnections on seasonal tree growth through local climate across the Mediterranean basin. Despite the constant link between the East Atlantic Pattern and temperature, synergies among teleconnections point to an east–west dipole in tree seasonal growth, driven by precipitation variability.

Height determination using GPS data, local geoid and global geopotential models [PDF]
, 1995 Orthometric heights are normally derived using the spirit levelling. This requires the spirit level equipment to be set up from point 10 point along a levelling line which is a time consuming and tedious task.
