Abstract. This study focuses on a single Mediterranean hurricane (hereafter medicane), to investigate its response global warming during the middle of 21st century and assesses effects warmer ocean atmosphere development. Our investigation uses state-of-the-art regional climate model WRF produce six-member, multi-physics ensembles. Results show that our setup simulates realistic cyclone track t...

[1] Sea level in the Mediterranean Sea over the period 1993–2011 is studied on the basis of altimetry, temperature, and salinity data and gravity measurements from Gravity Recovery and Climate Experiment (GRACE) (2002–2010). An observed increase in sea level corresponds to a linear sea level trend of 3.0 0.5mm/yr dominated by the increase in the oceanic mass in the basin. The increase in sea le...

Seasonal forecasts have improved during the last decades, mostly due to an increase of understanding of the coupled ocean-atmosphere dynamics, and the development of models able to predict the atmosphere variability. Correlations between different teleconnection patterns and severe weather in different parts of the world have also evolved during the last years. This paper evaluates the connecti...

Sixteen high-resolution marine aerosol (Na, SO4 ) records from spatially distributed International Trans Antarctic Scientific Expedition (ITASE) ice cores spanning the last ~200 years from the Pine Island-Thwaites and Ross drainage systems and the South Pole are used to examine sources (sea spray and frost flowers) and transport pathways of marine aerosols into West Antarctica. Factors contribu...

High aerosol levels pose severe air pollution and climate change challenges in Iran. Although regional optical depth (AOD) trends have been analyzed during the dusty season over Iran, specific factors that are driving spatio-temporal variations winter AOD influence of meteorological dynamics on remain unclear. This study analyzes long-term Iran period 2000–2020 using updated Modern-Era Retrospe...

This paper proposes a joint analysis of variations global sea-level pressure (SLP) and Earth’s rotation (RP), expressed as the coordinates pole (m1, m2) length day (lod). We retain iterative singular spectrum (iSSA) main tool to extract trend, periods, quasi periods in data time series. SLP components are weak seven quasi-periodic or periodic (?130, 90, 50, 22, 15, 4, 1.8 years), an annual cycl...

Based on the Australian Bureau of Meteorology (BoM) El Niño alert system, this study investigates atmospheric and oceanic conditions during developing years between 1982 2016. It is found that there a 2–5-month (subseasonal-to-seasonal) lag to establish steady low-level (or Southern Oscillation Index, SOI) response than Niño-pattern Sea Surface Temperature Anomaly (SSTA), which defined as criti...

abstract this research attempts to investigate the role of the blocking systems in surface cyclogenesis over eastern mediterranean sea; but particular attention is focused on the flood of iran during march 2000 over western states of iran as: hamadan, ilam, lorestan, kermanshah, kurdestan, zanjan, ghazvin.the data used for this research includes upper level and mean sea level pressure charts ev...
