Background PM10 atmosphere: In the seek of a multifractal characterization using complex networks

Quantifying Spatio-Temporal Dynamics of African Dust Detection Threshold for PM10 Concentrations in the Caribbean Area Using Multiscale Decomposition

“…In Table 1, one can observe that the minimum values are higher for the high dust season. This is due to the fact that a residual amount of dust remains in the atmosphere due to the continuous alternation between African easterly waves and dust outbreaks during that period (Plocoste et al, 2021c). As regards the maximum values, the behavior is different between both seasons.…”

Theoretical and Experimental Designs of the Planetary Boundary Layer Dynamics through a Multifractal Theory of Motion

“…Regarding the usage of the multifractal tunnel effect as a theoretical implement in atmospheric studies, to the best of our knowledge, this is a novel application; however, this effect was previously employed in a study explaining the "chameleon effect" of cholesterol [7]. In terms of merely applying multifractal theories to the atmosphere, a number of studies have been elaborated, such as one that deals with developing a multifractal random-walk description of turbulence itself, another study that analyzes the multifractal long-term characteristics of local temperature fluctuations, and a recent study that seeks to multifractally characterize atmospheric particular matter pollution [8][9][10]. It is noteworthy, however, that given the theoretical complexity of using multifractal techniques, especially in a scientific field such as atmospheric studies, which is already marked by added difficulties in the form of chaos and scaling issues, there are not many current works that explore the connections between multifractality and atmospheric fluid dynamics.…”

Wet scavenging process of particulate matter (PM10): A multivariate complex network approach

“…Figure 3 shows that the standard deviations exhibit their lowest values from October to April. Thus, marine aerosols are one of the primary constituents of the P M 10 background atmosphere (Plocoste et al, 2021a). The ITCZ movement toward the north generates precipitation carried by trade winds during the boreal summer (the rainy season) (Giannini et al, 2000;Muñoz et al, 2008).…”

“…Due to the impact on respiratory and cardiovascular diseases, diminishing P M 10 concentrations after dust outbreaks is crucial (Gurung et al, 2017;Zhang et al, 2017;Momtazan et al, 2019;Feng et al, 2019). African Easterly Waves (AEWs) (Prospero and Carlson, 1981;Plocoste et al, 2021a), which precede and follow the dust plumes, are the principal generator of precipitation during the high dust period (Dominguez et al, 2020) and regulate P M 10 concentrations in the Caribbean area.…”
