Past studies have demonstrated a significant relationship between the phase and amplitude of the Northern Annular Mode (NAM) and both Arctic sea ice and high-latitude snow cover during boreal autumn. However, those studies have considered these forcings separately. Here we consider the collective effect of Arctic sea ice and snow cover variability for producing skillful subseasonal forecasts fo...

Based on case studies, the development of low-pressure systems leading to extreme precipitation events reveals common characteristics. They highlight co-evolution sea surface temperature (SST) anomalies and clustering mesoscale convective in characteristic period ranges according harmonic modes annual declination sun. This suggests a quasi-resonance heat exchanges ocean atmosphere during cyclog...

several previous studies of adults have reported that the amplitudes of the sural and superficial radial nerve (sn and srn) action potentials are larger with antidromic than with orthodromic recordings. however, this difference has not been documented in children. this study evaluated the amplitudes of sn and srn sensory nerve action potentials (snaps), obtained with antidromic and orthodromic ...

The variance of time series records relating to ENSO, such as the interannual anomalies or bandpass filtered components of equatorial Pacific SST indices, provides one approach to quantifying changes in ENSO amplitude. Robust assessment of the significance of changes in amplitude defined in this way is, however, hampered by uncertainty regarding the sampling distributions of such variance metri...

The aim of this paper is to present an experimental configuration which enables the use of the pyroelecmc transducer in the front detection configuration. This configuration has been applied to the study of thermal parameters in the vicinity of two phase transitions of 9CB liquid crystal. Anomalies have been found in the phase of the photopyroelecmc signal near the phase transitions. Strong non...

Surface quality including surface roughness and edge chipping is a key process measure in micro ultrasonic machining (Micro-USM) as an efficient process for micromachining of hard and brittle materials. Process parameters such as ultrasonic vibration amplitude, static load, type of tool material, type and size of abrasive particles and slurry concentration can influence the surface quality. How...

A study is made of the relations between geomagnetic and geoelectric field variation, Earth-surface impedance, operational interference (“anomalies”) experienced on electric-power systems across contiguous United States during 13–14 March, 1989, magnetic storm. For this, a 1-min-resolution sequence maps constructed from magnetometer time series acquired at ground-based observatories. Induced ar...

In this paper, we focused on the characteristics of seismo-ionospheric effects related to two successive earthquakes, namely, earthquakes in 2022 Taitung Sea, Taiwan, China, with magnitudes (M) 6.7 and 6.3, at 23.45° N, 121.55° E 23.39° 121.52° same focal depth 20 km, which were detected by China Seismo-Electromagnetic Satellite (CSES). By applying sliding interquartile range method electron de...
