Bão bụi khủng khiếp ’made in China' vần quanh Trái đất
hững nhà khoa học Nhật bản lần đầu tiên phát hiện hiện tượng lạ lùng: những đám mây được tạo bởi một cơn bão bụi khổng lồ và tồn tại lâu đến mức bay quanh hơn một vòng trái đất. Cơn bão bụi này xuất phát từ sa mạc Taklimakan ở tây bắc Trung Quốc (xem Hình 1) và di chuyển vòng quanh trái đất suốt 13 ngày. Với bán kính chỉ khoảng 1.9 dặm nhưng cơn bão bụi lại có độ cao tới 1,242 dặm.
