The document discusses scatterometry and its unique ability to measure ocean wind and stress. Scatterometers send microwave pulses to measure ocean surface roughness caused by small waves in equilibrium with wind stress. This allows measurement of wind and stress vectors, which is unique to scatterometry. It also discusses using equivalent neutral winds from scatterometry to study various ocean-atmosphere phenomena like hurricanes, monsoons, and air-sea interactions.

A Possible Relationship between Gravitational Variations and Earthquakes in C...inventionjournals
An earthquake is not simply a sudden movement of the earth's crust, but the final product of a process that may have begun much earlier. In an area subject to tectonic stress, there can be precursory phenomena since this is where crustal deformation accumulates. A variation in gravity, measured instrumentally to the sixth decimal place, is one of the possible candidates to analyse measurable signals that precede, accompany and follow a seismic tremor. To verify the relationship between the number of earthquakes, the energy released, and the variations in gravity, the sequence in Central Italy was examined, above all that of January 2017. Data from a gravimeter located about 270 kilometres from the epicentral areas have been modelled as Standard Deviation, obtained from gravity measurements (400) carried out on the respective days. This indicator, of a statistical and mathematical nature, indicates the degree of dispersion with respect to its mean value, taken as the average value of these gravity measurements, and shows a positive correlation with the number of daily earthquakes and the energy released by the seismic sequence of January 2017.

The Illustration of Mechanism and development of Atmospheric dynamic peripher...iosrjce
This research papers illustrates and justify the soil shifting and a pre determinant mechanism of
testing and real time analysis of soil composition and the behavior by concentric waveform generation and the
field effect of the concentric waves thus formed. The waveforms generated are being analyzed using a field wire
enclosure structure having a non conducting cylinder with circular magnetic field effect induction. The
electrical pulses being generated are plotted against fluid viscosity behavior. The research paper illustrates
with conclusion and analysis that a correlation simulation model is possible with fluid properties to generate
non obvious prediction mechanism to possible pulse generator.

Disturbances in Solar Wind Electrons during the Ascending Half of the Solar C...researchinventy
Ulysses achieved a solar orbit with an inclination of 80.200 , perihelion of 1.34 AU, aphelion of 5.4 AU and a period of 6.2 years. By comparing observations taken over nearly all heliolatitudes and two different intervals covering the same radial distances, we are able to separate the radial and latitudinal variations in the solar wind. This paper describes the detailed results of the studies devoted to the solar activity impact on the Earth’s upper atmosphere and ionosphere. The methods used in this study are based on the data driven from the Ulysses spacecraft. The primary objective of the Ulysses solar wind plasma investigation uses SWOOPS (Solar Wind Observations over the Poles of the Sun) instrument to investigate and establish bulk flow parameters and internal state conditions of the solar wind as a function of solar latitude. The electron temperature Te and the electron density Ne are found to exhibit a sharp enhancement during the ascending half of the solar cycle 23 (1996 – 2004)
Changes of Temperature Field in Storms Under Influence of Cold SurgeAI Publications
This study goal is to explore changes of the temperature field during storms operating in the East Sea under the influence of cold air over time. Studies on wave–current interaction have focused mainly on tropical cyclones, while less attention has been paid to other weather systems (Gong et al, 2018). Strong winds in coastal areas can cause dramatic changes in water level and currents, which influence wave height and direction, thereby increasing hazardous conditions (Sun et al, 2018). Wave parameters in the outer region of the typhoon are more sensitive to the current but less sensitive to the water elevation than those in the inner region of the typhoon (Hsiao et al, 2020). The results show that the temperature field in the storm under the influence of cold air has an asymmetrical distribution around the center.
