Abstract Earth’s orbit and rotation produces systematic variations in geomagnetic activity, most notably via the changing orientation of dayside magnetospheric magnetic field with respect to heliospheric (HMF). Aside from these geometric effects, it is generally assumed that solar wind near-Earth uniformly sampled. But changes intrinsic conditions space could arise due annual Earth heliocentric...

Compact radio sources exhibit scintillation, an interference pattern arising from propagation through inhomogeneous plasma, where scintillation patterns encode the relative distances and velocities of source, scattering material, Earth. In previous work, we showed that velocity repeating fast burst FRB20201124A could be measured by correlating spectra pairs, with low values timescale suggesting...

The hypothesis that Peruvian stratocumulus play an important role on both the annual mean and annual variations of sea surface temperature (SST) in the eastern equatorial Pacific is examined. The problem is addressed by performing sensitivity experiments using the University of California, Los Angeles, coupled atmosphere– ocean GCM with different idealized temporal variations of stratocumulus i...

Seasonal and annual precipitation anomalies, normalized with respect to the standard deviations are computed for stations between 30*S and 30N. It is established that the annual anomalies are normally distributed. Spatially averaged anomalies are computed for various regions and their representativeness confirmed. Correlations between the annual average normalized anomalies of the various regio...

the least squares harmonic estimation is applied to the hourly time-series of total electron contents (tec) derived from ionospheric models using seven years of gps observations processed by bernese software. the frequencies of dominant spectral components in the spectrum are estimated. we observe significant periodic patterns with periods of 24 h and its fractions 24h/n, n=2,…,11, which are th...

[1] A decade-long satellite altimeter data set is used to analyze the annual variations in the sea surface height (SSH) field northeast of the Hawaiian Islands. The annual harmonic amplitudes for the SSH and the along-island geostrophic flow are 2–4 cm and 2–4 cm s , respectively. Although these values are an order of magnitude smaller than the regional mesoscale eddy signals, the annual SSH si...

Four different data sources have been compared with respect to observations of the annual water storage variations in the region of Bangladesh. Data from satellite altimeters and river gauges estimates the variation in surface water storage in the major rivers of Bangladesh. The GRACE satellites measure the integrated mass change and hence the terrestrial soil moisture variations, which can als...
