GPS network observation of traveling ionospheric disturbances following the Chelyabinsk meteorite blast

We use the Global Positioning System (GPS) network in northwest China and central Asia to monitor traveling ionospheric disturbances (TIDs), which were possibly excited by the large meteorite blast over Chelyabinsk, Russia, on 15 Februar...

Internal Variability Reshapes Externally Forced Trends in Marine Cold‐Air Outbreak Frequency Over the Northern Hemisphere

Abstract Marine cold‐air outbreaks (MCAOs) are key conduits of polar‐to‐midlatitude air‐mass exchange, strongly modulating wintertime air–sea heat fluxes, storm‐track activity, and the development of extreme cold conditions over adjacent co...

A comparative study on chaoticity of equatorial/low latitude ionosphere over Indian subcontinent during geomagnetically quiet and disturbed periods

In the present study, the latitudinal aspect of chaotic behaviour of ionosphere during quiet and storm periods are analyzed and compared by using GPS TEC time series measured at equatorial trough, crest and outside crest stations over India...

Topology and seasonal evolution of the network of extreme precipitation over the Indian subcontinent and Sri Lanka

This paper employs a complex network approach to determine the topology and evolution of the network of extreme precipitation that governs the organization of extreme rainfall before, during, and after the Indian Summer Monsoon (ISM) season...

New trends in active faulting studies for seismic hazard assessment

Interplanetary external driven quasidynamo as the origin of geomagnetic jerks correlated with length of day and gravity anomaly

We report phenomenological inevitable correlation between the Sun’s magnetic field oscillation through the Earth and the Jupiter, with sinusoidal geomagnetic jerks observed at the Earth, additionally aligned with the gravity and length of d...

Fluctuation-Response Relation and modeling in systems with fast and slow dynamics

We show how a general formulation of the Fluctuation-Response Relation is able to describe in detail the connection between response properties to external perturbations and spontaneous fluctuations in systems with fast and slow variables. ...

Spatial and temporal distribution of vertical ground movements at Mt. Vesuvius in the period 1973-2009

Since the early ’70s vertical ground movements at Mount Vesuvius area have been investigated and monitored by the Osservatorio Vesuviano (Isti-tuto Nazionale di Geofisica Vulcanologia - Osservatorio Vesuviano since 2001). This monitoring be...

Impact of Urbanization on Cloud Characteristics over Sofia, Bulgaria

Urban artificial surfaces and structures induce modifications in land–atmosphere interactions, affecting the exchange of energy, momentum, and substances. These modifications stimulate urban climate formation by altering the values and dyna...

Verification of the multi-layer SNOWPACK model with different water transport schemes

The widely used detailed SNOWPACK model has undergone constant development over the years. A notable recent extension is the introduction of a Richards equation (RE) solver as an alternative for the bucket-type approach for describing water...

Assessing economic impacts of future GLOFs in Nepal's Everest region under different SSP scenarios using three-dimensional simulations

This study investigates simulated glacial lake outburst floods (GLOFs) at five glacial lakes in the Everest region of Nepal using the three-dimensional model OpenFOAM. It presents the evolution of GLOF characteristics in the 21st century co...

Changes in the Association between GDP and Night-Time Lights during the COVID-19 Pandemic: A Subnational-Level Analysis for the US

Night-time light (NTL) data have been widely used as a remote proxy for the economic performance of regions. The use of these data is more advantageous than the traditional census approach is due to its timeliness, low cost, and comparabili...

Air distribution to reduce nitrogen oxide emissions in the furnace of a boiler with tangential combustion scheme

Relevance. Determined by the importance of analyzing the combustion characteristics and factors affecting the emission of nitrogen oxides (NOx) in the furnace chamber of pulverized coal-fired power boiler unit when installing tertiary air n...

Analytical solutions of steady-state temperature field for large-section freezing with rectangular layout of single-ring holes

The temperature field is the basis for assessing the mechanical state and water-sealing performance of the frozen wall, which is an important research direction of the artificial freezing theory. For the freezing pipes in the form of a clos...

Using stable isotopes and major ions to identify recharge characteristics of the Alpine groundwater-flow dominated Triglavska Bistrica River

Triglavska Bistrica is a typical Alpine river in the north-western part of Slovenia. Its recharge area includes some of the highest peaks in the Julian Alps. The hydrogeological conditions and flow of the river depend largely on groundwater...

Dynamic characteristics of unsaturated loess and their influences on ground vibration parameters of sites

The dynamic triaxial tests on the unsaturated loess in Xiji region of Ningxia under different water contents are carried out. Based on the analysis of the influences of water content on the dynamic characteristics of loess, the influences o...

Nature of Paleozoic Basement of the Catalan Coastal Ranges (Spain) and Tectonic Setting of the Priorat DOQ Wine Terroir: Evidence from Volcanic and Sedimentary Rocks

The Paleozoic volcano-sedimentary rocks within the structural basement of the horst-and-graben system of the Catalan Coastal Ranges (CCR) are composed of black shale, volcaniclastic sediments, lava flows, sills and lithocrystalloclastic tuf...

Influence of valley topography on earth pressure of high-fill arch culvert

High-fill culverts placed in valley topography have a complex earth pressure distribution law due to their locations around culverts in various valley topography conditions. In order to investigate the influence of valley topography on the ...
