Changes in number and intensity of world-wide tropical cyclones [PDF]

arXiv, 2007
Bayesian statistical models were developed for the number of tropical cyclones and the rate at which these cyclones became hurricanes in the North Atlantic, North and South Indian, and East and West Pacific Oceans. We find that there is small probability that the number of cyclones has increased in the past thirty years.

Space climate and space weather over the past 400 years: 2. Proxy indicators of geomagnetic storm and substorm occurrence

Journal of Space Weather and Space Climate, 2018
Using the reconstruction of power input to the magnetosphere presented in Paper 1 Lockwood  et al. [J Space Weather Space Clim 7 (2017a)], we reconstruct annual means of the geomagnetic Ap and AE indices over the past 400 years to within a 1-sigma error ...

Distribution and Recovery Phase of Geomagnetic Storms During Solar Cycles 23 and 24 [PDF]

arXiv
Coronal mass ejections (CMEs) and Stream Interaction Regions (SIRs) are the main drivers of intense geomagnetic storms. We study the distribution of geomagnetic storms associated with different drivers during solar cycles 23 and 24 (1996-2019). Although the annual occurrence rate of geomagnetic storms in both cycles tracks the sunspot cycle, the second

The influence of space weather on ionospheric total electron content during the 23rd solar cycle

Journal of Space Weather and Space Climate, 2013
This paper presents a new empirical model for predicting the daily mean ionospheric Total Electron Content (TEC) at a given latitude from only one solar index as input. For the development of the model we take advantage of the availability of 15 years of

Investigation Of The Hydro-Meteorological Hazards Along The Bulgarian Coast Of The Black Sea By Reconstructions Of Historical Storms [PDF]

Journal of Environmental Protection and Ecology, Vol. 16, No 3, 1005-1015 (2015), 2015
Information about the hydro-meteorological parameters during the extreme sea storms is of significant importance for the sustainable development in the context of flood risk for the coastal areas. Usually there is a lack of sufficiently long history of instrumental measurements of the extreme winds, waves and storm surges.

A Lagrangian Perspective on the Growth of Midlatitude Storms [PDF]

arXiv
Extratropical storms dominate midlatitude climate and weather and are known to grow baroclinicaly and decay barotropicaly. Traditionally, quantitative climatic measures of storm growth have been mostly based on Eulerian measures, taking into account the mean state of the atmosphere and how those affect eddy growth, but they do not consider the ...

Understanding the detectability of potential changes to the 100-year peak storm surge [PDF]

arXiv, 2017
In many coastal communities, the risks driven by storm surges are motivating substantial investments in flood risk management. The design of adaptive risk management strategies, however, hinges on the ability to detect future changes in storm surge statistics.

Visualization of Protein Sorting at the Trans-Golgi Network and Endosomes Through Super-Resolution Imaging

Frontiers in Cell and Developmental Biology, 2019
The trans-Golgi network (TGN) and endosomes are essential protein sorting stations in the secretory transport pathway. Protein sorting is fundamentally a process of spatial segregation, but the spatial relationships among the proteins that constitute the
