Dicha nube puede identificarse en la imagen del sat\u00e9lite GOES 16, publicada por la Comisi\u00f3n Nacional del Agua.<\/strong><\/em><\/p>\n\n\n\n

El Centro Nacional de Prevenci\u00f3n de Desastres (Cenapred) report\u00f3 que una nube de polvo proveniente del Sahara se ubica sobre el Oc\u00e9ano Atl\u00e1ntico, el Mar Caribe, y en pocas cantidades en el Golfo de M\u00e9xico, en las cercan\u00edas de la Pen\u00ednsula de Yucat\u00e1n.<\/p>\n\n\n\n

Dicho organismo dependiente de la Coordinaci\u00f3n Nacional de Protecci\u00f3n Civil, aclar\u00f3 que las tormentas de arena y polvo son fen\u00f3menos meteorol\u00f3gicos comunes en las regiones \u00e1ridas y semi\u00e1ridas, <\/p>\n\n\n\n

Precis\u00f3 que la cantidad de polvo que ingresa a M\u00e9xico depende de la intensidad del viento y de la concentraci\u00f3n del material sobre las regiones \u00e1ridas de \u00c1frica septentrional, la pen\u00ednsula ar\u00e1biga, Asia central y China.<\/p>\n\n\n\n

El Centro plante\u00f3 que el polvo – se caracteriza por tornarse gris\u00e1ceo durante el d\u00eda, con atardeceres rojizos y poca nubosidad- ingresa por lo general por la vertiente oriental y sureste del pa\u00eds, con un efecto directo en la nubosidad y las lluvias, pero la Sierra Madre Oriental es una barrera natural contra su ingreso al centro del territorio mexicano, al que s\u00f3lo logran llegar peque\u00f1as concentraciones.<\/p>\n\n\n\n

Estudios cient\u00edficos han demostrado que en la cuenca del Caribe, el 30% de las bacterias aisladas del polvo, presentes en el aire, son pat\u00f3genos capaces de transmitir infecciones a plantas, animales o personas. <\/p>\n\n\n\n

El National Oceanic & Atmospheric Administration (NOAA, por sus siglas en ingl\u00e9s) explica que la capa del polvo del Sahara \u201ces una masa de aire muy seca y cargada de polvo que se forma sobre el Desierto del Sahara a finales de la primavera, durante el verano y temprano en el oto\u00f1o, y se mueve usualmente hacia el oc\u00e9ano Atl\u00e1ntico Norte cada 3-5 d\u00edas.<\/p>\n\n\n\n

Esta capa puede extenderse verticalmente entre los 1, 500 a 6, 000 metros (5,000 a 20,000 pies) de altura en la trop\u00f3sfera y est\u00e1 relacionada con cantidades grandes de aire muy seco y cargado de polvo\u201d. <\/p>\n\n\n\n

Igualmente, esto puede tener un efecto negativo importante sobre la intensidad de los ciclones tropicales y su formaci\u00f3n que debilita el cicl\u00f3n tropical al suprimir las corrientes de aire ascendente de la tormenta, y los vientos horizontales que transportan el polvo cambian significativamente.<\/p>\n\n\n\n

Ante la eventual concentraci\u00f3n de polvo, el Cenapred recomend\u00f3 a la poblaci\u00f3n evitar exponerse, resguardarse, cerrar las entradas de aire a los cuartos durante las tormentas, y de ser indispensable mantenerse a la intemperie, llam\u00f3 a usar lentes, cubrebocas o pa\u00f1uelo, sobre todo quienes padecen males respiratorios, cubrir fuentes de agua como pozos, recipientes o estanques y utilizar gafas de sol.<\/p>\n\n\n\n
