Abstract Mean wintertime temperatures (December, January, February) recorded during the period 1905–2000 at 18 weather stations distributed across Egypt were analysed to reveal spatial and temporal patterns of long‐term trends. The relationship between winter atmospheric circulation indices temperature in is examined using correlation analysis. represented by four indices: well‐known El Niño–southern oscillation (ENSO), North Atlantic (NAO) index, East Atlantic–West Russia (EAWR) (EA) index....

Abstract Variations of summer temperature over Egypt have been studied using the data 19 stations. The analysis these shows that surface is a stable climate element where its coefficient variation (COV) found to be low during summer. time sequence cumulative seasonal mean (CSM) shown exhibit bounded, oscillatory, nonperiodic behavior. boundedness oscillation supports notion compensation; i.e. spells cold must eventually follow warm. trend series our stations striking positive values last 20...

ABSTRACT Sea surface temperature ( SST ) is an important oceanic variable that impacts regional and global climate. This paper examines the relation of summer (June to August) air SAT variability over Saudi Arabia (1948–2013) with Atlantic, Pacific Indian Oceans. The shows abrupt increase around 1980s (i.e. 1986). Partial correlations between different indices indicate Indo‐Pacific warm pool IPWP has a more significant effect on than does tropical North Atlantic TNA ), South TSA or Western...

Abstract Based on generated time series of the central pressure subtropical high, behaviour this atmospheric centre action has been examined since 1950 with regard to inter‐annual variations, persistence, linear trends, abrupt change, spectral analysis and interactions. The year‐to‐year variations in high are considerable. pronounced strengthening during approximately last 20 years is its most remarkable feature. Variations high's intensity seem follow a cyclic pattern. Statistically...

Abstract The windshear (WS) or wind gradient is a short-lived microscale meso-gamma weather phenomenon and potentially very dangerous for aviation everywhere. This research presents the calculation of WS frequency intensity from radiosonde data at six airport stations namely Abha, Jeddah, Madinah, Tabuk, Riyadh, Dammam in Saudi Arabia period 1991–2020. indicate that number severe increased suddenly 2015 below 30 m level all except Riyadh there no sudden increase. At other levels, light...

The current study looks at how the characteristics of Arabian Sea tropical cyclones (TCs) change over time. results show that in pre-monsoon (April–June) and post-monsoon (October–December), activity TCs > 34 knots, including cyclonic storm (CS), severe (SCS), very (VSCS), extreme (ESCS), super (Sup. CS), has significantly increased, while tendency < depressions deep (Ds) only slightly increased. Most TC first two decades (1982–2001) activated on eastern side, last (2002–2021), there...

Abstract The summer season (June–July–August) surface air temperatures (SATs) over Saudi Arabia and its association with the atmospheric circulation cells were identified analysed using NCEP‐NCAR reanalyses NOAA extended reconstructed sea temperature (SST) datasets from 1948 to 2016. pressure vertical velocity divergent wind utilized determine such as Hadley, Walker, Ferrel cells. Possible mechanisms associated changes in SAT investigated, particular focus on uppermost lowermost summers....

Variability of wintertime surface air temperature (SAT) in the Kingdom Saudi Arabia (KSA) is studied. The study based on time series over thirty one years length (1978-2008). For analysis, we use coefficient variability (COV) Mann-Kendal statistical test, running mean and cumulative annual (CAM). for SAT decreases gradually from north to south KSA. higher values COV occur northern northeastern KSA; there are due effect traveling Mediterranean depressions their interaction with inverted-V...

Abstract A robust subtropical circulation index (SCI) is defined as the difference between North Atlantic high and Indian monsoon low. The SCI negatively correlated to air temperatures over Egypt associated with large‐scale climate indices of tropical sector. Copyright © 2005 Royal Meteorological Society

<title>Abstract</title> The windshear (WS) or wind gradient is a short-lived microscale meso-gamma weather phenomenon and potentially very dangerous for aviation everywhere. It commonly observed near microburst downburst caused by different factors including thunderstorms may increase in the era of climate change. This research presents calculation WS frequency intensity from radiosonde data at six stations Saudi Arabia period 1991-2020. were used to calculate light, moderate, strong, severe...

Surface air temperature (SAT) variability is investigated for advancing our understanding of the climate patterns over Kingdom Saudi Arabia (KSA). SAT reveals significant warming trends, particularly from 1994 onward, as demonstrated by nonlinear and linear trend analysis. This linked to global patterns, which serve indicators studying effects change on surface across KSA. The empirical orthogonal function (EOF) method employed analyzing due its effectiveness in extracting dominant during...

Global climatic circulation indices play a major role in determining regional and global climate conditions. These atmospheric patterns exhibit substantial variability, covering wide geographical area affecting weather-related events. The primary goal of this study was to examine characterize various variability during the 1950 2020 period (El Niño Southern Oscillation, ENSO; Oscillation Index, SOI; North Atlantic NAO; Meridional Mode, AMM; Indian Ocean Dipole, IOD). Also, article try...
