“…A relatively high spatial resolution of satellite-derived SST and Chl-a data were useful in delineating the seasonal variability of the quasi-permanent biophysical coupling induced particularly by the regional surface wind stress curl pattern. The results of this study were consistent with those from previous ones (Sánchez-Valasco et al, 2006;Pardo et al, 2013;Coria-Monther et al, 2014;Turrent and Zaitsev, 2014); nonetheless, new details have emerged to our knowledge and understanding of common and unique features of seasonal variability in the ocean-atmospheric system of the BLPZ. Harmonic fit displayed coherent spatial patterns dominated by the seasonal cycle showed in Figure 3 (bottom panels) of warming and cooling of surface waters and their effect on biological productivity; this showed us a view of this biophysical coupling observed along the bay and revealed the extent to which these variables could be affected particularly by diverse forcing, such as regional wind pattern, local income solar radiation, air-sea heat exchange, and others.…”

“…(1) hydrographic variability in the southern GC; (2) high solar radiation (high evaporation rates); and (3) local wind forcing: strong northwesterly winds during winter and early spring with values ~ 8 to 12 m s -1 and the onset and intensity of the North American Monsoon with moderate south and southeastern winds with magnitudes ~ 4 m s -1 in summer and early fall (Marinone et al, 2004;Turrent and Zaitsev, 2014). This wind pattern, jointly with the coastal orientation and the orographic continental effect on BLPZ, could generate advection and coastal currents in winter and cyclonic surface circulation throughout summer and early fall (Jiménez-Illescas et al, 1997;Sánchez-Velasco et al, 2006;Coria-Monter et al, 2014).…”

En este estudio se examinan, a partir de imágenes de satélite derivadas del sensor MODIS-Aqua, las climatologías mensuales de la temperatura superficial del mar (TSM), clorofila superficial (Chl-a) y su relación con el rotacional del esfuerzo del viento (Cross-Calibrate Multi-Plataform, CCMP) en la bahía de La Paz, ubicada en el suroeste del Golfo de California, una región con alta productividad biológica e importante variabilidad estacional. El ajuste armónico aplicado a las climatologías mensuales de estas variables indica un mejor ajuste con los constituyentes anual y semianual. La amplitud anual es la señal dominante tanto en la TSM como en la Chl-a y corresponde al ciclo estacional de calentamiento y enfriamiento en toda la bahía, asociado con la afluencia de aguas costeras ricas en nutrientes y el intercambio de agua entre la bahía y el Golfo de California. Un análisis de funciones empíricas ortogonales (FEO) identifica los patrones anual y semianual del ciclo estacional que responden al forzamiento del viento. La FEO

“…We must recognize that the extension of the inland penetration of opposing sea breezes cannot be addressed with the results derived from the present study. In narrower peninsulas, such as Baja California (Turrent and Zaitsev, 2014) and Florida (Blanchard and López, 1985) the regular collision of opposing sea breeze fronts is an important process, which is more dominant during the summer.…”

El equilibrio entre los fenómenos atmosféricos sinópticos y la brisa marina puede influir profundamente en la circulación en las regiones costeras. En este artículo se describen los patrones cuasi permanentes de dicha variabilidad en el campo de vientos de superficie de la Península de Yucatán. Para lograr esto se realizó un análisis de funciones empíricas ortogonales complejas (CEOF) sobre 10 años (mayo 2007-mayo 2017) de modelaciones de vientos en superficie del modelo North American Mesoscale Forecast System (NAM). Se aplicó un filtro paso alto/paso bajo a las series de tiempo obtenidas del CEOF, para estudiar el comportamiento temporal de alta y baja frecuencia de los modos. Los resultados muestran que, de octubre a marzo, los frentes fríos dominan en dos patrones diferentes (dos primeros modos), lo cual amortigua los vientos locales que muestran una mayor amplitud durante la noche (brisas de tierra) que durante el día (brisas marinas). La influencia de los sistemas tropicales al final de esta temporada, aunque menor, es notable (tercer modo). De abril a septiembre, la península está dominada por brisas marinas acentuadas sobre la plataforma occidental (primer modo), mientras que las brisas terrestres exhiben una menor dominancia que las brisas marinas (tercer modo). En este periodo, los frentes fríos y los sistemas tropicales (modo 2) ejercen una influencia más suave sobre los vientos locales. Un fenómeno distintivo visto en las altas frecuencias del segundo modo durante este periodo es la ocurrencia de brisas marinas en toda la península. Los resultados de este trabajo tienen implicaciones importantes para la dispersión de contaminantes atmosféricos, la generación de oleaje por el viento y la erosión costera, entre otros.

“…Given the importance of moisture and dust transport in the desert, studies on the circulation of wind in the BCP have focused mainly on the summer. These show that surface wind responds to: (1) The thermal contrast between the Pacific Ocean (PO) and the GC [21,26,28,29], (2) orography of the BCP [21,26,[30][31][32], the difference in surface air temperature between the margins of the BCP (peninsular PO margin and GC) [21], and the high-pressure belt in the northern hemisphere [24].…”

The Baja California Peninsula, a Significant Source of Dust in Northwest Mexico

Despite their impacts on ecosystems, climate, and human health, atmospheric emissions of mineral dust from deserts have been scarcely studied. This work estimated dust emission flux (E) between 1979 and 2014 from two desert regions in the Baja California Peninsula (BCP) using a modified dust parameterization scheme. Subsequently, we evaluated the processes controlling the variability of E at intra- and interannual scales. During the period 1979–2014 peak E were generally recorded in summer (San Felipe) and spring (Vizcaino), and the lowest emissions occurred in autumn (San Felipe) and winter (Vizcaíno). Intra- and interannual variability in E was associated with fluctuations in wind speed and direction, precipitation, and soil moisture, which, in turn, were controlled by the seasonal displacement of the North Pacific high-pressure center. Key drivers of the interannual variability of E are strong El Niño Southern Oscillation (ENSO) events. These climatic events and the hydrometeorological variables mentioned above played a major role in the onset and occurrence of dust events, with the highest annual emissions at Vizcaíno. Besides, a lag of 19 months (San Felipe) and 21 months (Vizcaino) was recorded between the occurrence of relevant E and ENSO events, apparently in response to the effect of this climatic event on precipitation. The climate variability of E in both desert regions was evidenced by the positive trends associated with increases in wind speed and air temperature, and with decreases in precipitation and soil moisture. Finally, our findings suggest that the BCP should be considered as a significant source of dust for the regional inventory of particulate matter emissions from the Earth’s surface.
