For one picture of Pacific towards October ending, two storms look different well well. Clouds form tight circle near Mariana Islands. Farther north, one long stretch of cloud bend towards Alaska. On 3 November NASA Earth Observatory explain how satellites capture two different stages for storm life.
Na EPIC camera on top DSCOVR satellite take the wide picture on 29 October. The round storm na Super Typhoon In-fa. Clouds for north include wetin remain of Typhoon Champi. The storm don change as e reach the route wey storms dey pass over Bering Sea.
One day later, MODIS instrument on NASA Terra satellite take closer picture of In-fa west of the islands. You fit see wide eye inside cloud wey form almost complete circle. Those long cloud bands wey dey twist comot from plenty tropical storms hardly show. Weather experts dey call storms with these features annular.
That description no fit explain wetin dey happen farther north. Tropical storms get warm centre and draw energy from warm water. Outside the tropics, the difference between warm air and cold air next to each other fit give storm energy. Wetin remain of Champi don pass through that change.
As the system dey change, wind fit cover more ground. E no mean say wind speed for any one place must don rise. NASA weather expert Gary Partyka say storm for probably form over Bering Sea anyway, but e look like wetin remain of Champi help am gain strength.
Wetin e mean for you: when you see satellite picture with storm name, check when dem take am and the stage wey the storm don reach. These pictures show conditions for 29 and 30 October. Dem explain clouds over Pacific. Dem no give weather forecast for Nigeria.
