High frequency and VHF radio propagation data, solar and geomagnetic real-time and historic data, sunspot activity reports, as well as forecasts. A comprehensive propagation resource compiled by Tomas Hood, editor of the propagation columns of CQ, CQ VH
We then check whether these patterns might mimic the recent solar magnetic activity by investigating the evolution of the energy in the Sun's large-scale dipolar magnetic field using the Wilcox Solar Observatory data. The cosmogenic radionuclide data analysis shows that \\({\\approx}\\,71\\ \...
An explanation is suggested for the north-south asymmetry of the polar magnetic field reversal in the current cycle of solar activity. The contribution of the Babcock-Leighton mechanism to the poloidal field generation is estimated using sunspot data for the current activity cycle. Estimations are ...
The current activity minimum has attracted considerable interest because of its unusual duration and depth. This raises the question: what might be happening beneath the surface where the magnetic activity ultimately originates? The surface activity can be linked to the conditions in the solar ...
We study the effect of the solar-cycle and geomagnetic activity on the composition and their maximum positions of the ring current ions by using the energetic particle data obtained by MICS instrument on board CRRES satellite and other research results of AMPTE. Observations show that the number ...
a period of years.Mizuno and White (1983)reported identification of a quasi-stationary meander pattern (Kuroshio Meander) in the Kuroshio Extension in the vicinity of the Shatsky Rise (160°E). The Kuroshio Meander becomes unstable as a consequence of increased eddy activity and ring production....
The skies over New Jersey have been buzzing with mystery as residents continue to report unusual activity involving drones at night. After weeks of speculation, ...Read More Energy Industry News Disaster strikes: Russian tanker splits in half, spilling oil into Kerch Strait ...
In the past – and in some regions still today – large volumes of waste have been buried in landfill waste sites. This waste, as it is covered and compacted, will over time start to generate methane gas as a result of the activity of natural microbes in the soil. This methane is then...
An effort was made to situate economic activity. Gridded data on heat-induced worker productivity losses were matched with population masks to obtain population-weighted impacts on worker productivity. We used the gridded UN WPP-adjusted population count data v4.11, provided by the Socioeconomic Dat...
Some current analyses conclude that volcanoes and solar activity explain quite a considerable amount of the observed variability in the period from the seventeenth to the early twentieth century’s, but that they cannot be invoked to explain the rapid warming in recent decades. 问题...
