“…The climate in LSB is subject to the contrasts of the Mediterranean climate concomitant with oceanic influences which give it particular climatic rhythms on the one hand, and on the other hand the north-west winds, meeting the Iberian chains (Spain) arriving dry in the north-west of Morocco. In addition, there is a simple succession of two climatic environments (cyclonic and anticyclonic), which have a remarkable influence on the inter-annual variability of the climate in Morocco (Driouech et al 2021) and in particular in the LSB (Hakam et al 2022b).…”

“…The spatio-temporal evolution of droughts in the LSB is controlled by landscape heterogeneity and specific climatic events such as extreme weather anomalies and large-scale atmospheric circulations (Lamb and Peppler 1987;Zamrane, Mahé and Laftouhi 2021;Hakam et al 2022b). Some studies have demonstrated an anti-correlation of rainfall in Morocco, especially in the northwestern part, and the North Atlantic Oscillation (NAO) (Marchane et al 2016;Driouech et al 2021).…”

The Lower Sebou Basin, placed in a Mediterranean climate, has the particularity of being exposed to the influence of disturbances from the Atlantic Ocean, making periods of drought and climatic phenomena variable in space and time. Applying the world's most recognized drought indices, shows that the duration, frequency and severity of droughts have increased since the start of the 21st century. These results revealed and placed in the even wider regional climatic context, including the two dominant atmospheric oscillations such as the North Atlantic Oscillation (NAO) and the Mediterranean Oscillation (MO), suggest that the significant drought trends determined are correlated with the relative facts of the two oscillations.

“…The work of Knippertzet al (2003) [22] showed that precipitation in the northwest of the country shows a clear link with atmospheric pressure variations over the North Atlantic during boreal winter (DJF), with a relatively strong negative correlation with the NAO. Other works show that winter precipitation is negatively correlated with the NAO all over Morocco [23][24][25]. The negative phase normally leads to increased precipitation, and the positive phase is usually linked to precipitation deficits [26,27].…”

“…Different studies have been carried out in order to determine the relationship between the large-scale patterns of atmospheric circulation and Moroccan precipitation variability [22,25,[54][55][56]. Here, correlations of monthly precipitation for different stations are calculated with the NAO and the WeMo indices.…”

Morocco is characterized by a semi-arid climate influenced by the Mediterranean, Atlantic, and Saharan environments, resulting in high variability in rainfall and hydrological conditions. Certain regions suffer from insufficient understanding concerning the spatiotemporal patterns of precipitation, along with facing recurrent periods of drought. This study aims to characterize the current trends and periodicities of precipitation in west-central Morocco at monthly and annual scales, using data from six rain gauges. The link between monthly precipitation and both the North Atlantic Oscillation (NAO) and the Western Mediterranean Oscillation (WeMO) indices was tested to identify potential teleconnections with large-scale variability modes. The results reveal interannual variability in precipitation and climate indices, while showing decreasing insignificant trends in annual precipitation. On a monthly scale, temporal precipitation patterns are similar to the annual scale. Furthermore, a remarkably robust and significant component with a periodicity of 6–8 years emerges consistently across all monitoring stations. Intriguingly, this band exhibits a more pronounced presence on the plains as opposed to the mountainous stations. Additionally, it is noteworthy that the NAO modulated winter precipitation, whereas the influence of the WeMO extends until March and April. This mode could be linked to the fluctuations of the WeMO from 1985 to 2005 and, subsequently, to NAO variations. Indeed, this is consistent with the strong significant correlations observed between rainfall and the NAO/WeMO. This study serves as a baseline for future research aiming to understand the influence of climate indices on rainfall in the North African region.

The World Health Organization (WHO) estimates 30,000 new cases of visceral leishmaniasis (VL) and more than one million cases of cutaneous leishmaniasis (CL) annually. Geographically, these diseases are more widespread, and cases are now reported in areas where the disease was not previously endemic. 9 As in most Mediterranean countries, leishmaniasis represents a severe public health problem in Morocco. 11 It is the first group of vector-borne diseases, whether they are zoonotic or anthroponotic, visceral or cutaneous. 12 Leishmaniasis is among the infectious diseases that must be reported according to Ministerial Order No. 683-95 of March 31, 1995. 13,14 Zoonotic leishmaniasis, caused by Leishmania infantum, is rife throughout the Mediterranean region. Species of the subgenus Larroussius, Phlebotomus (Larroussius) Perniciosus, and Phlebotomus (Larroussius) longicuspis, are the proven and suspected vectors of visceral leishmaniasis. 15 The distribution and transmission of the disease are closely linked with the vector, ecological, and bioclimatic factors. 16,17,18 These disease vectors and their relationship to environmental factors (such as temperature, humidity, and vegetation cover) must be explored and studied to conduct appropriate monitoring and control strategies. In this context, this research was conducted to investigate the spatiotemporal dynamics of Phlebotomus perniciosus (Diptera: Psychodidae) and characterize its habitats using satellite images in the city of Fez.
