Near the tropopause, as the air moves polewards in the Hadley cell, it is turned eastward by the Coriolis effect, creating the subtropical jet streams that flow from west to east.

The Swiss-English team, which had been traveling due east for days, headed southeast on Saturday to get into position to catch the Subtropical jet stream south of Hawaii by Monday or Tuesday.

Unseasonably chilly weather will persist in the Deep South, given that the northward advance of warm, tropical air will still be impeded by a strong, west-to-east subtropical jet stream over the southern tier states.

The subtropical jet stream, which typically has its origin near the Equator and is usually even higher than its mid-latitude cousin, can influence weather across the United States, especially southern portions of the country.

The 1998 El Nino has driven both the polar jet stream and the subtropical jet stream northward, leaving Texas in the middle of the subtropical jet stream, which is characterized by Pacific storms and tornadoes.

One of El Nino's signatures since it reappeared in December has been a strong subtropical jet stream, a high-altitude river of air that flows off the Pacific and races across the southern part of North America.

The balloon is currently traveling at a speed of about 70 kilometers per hour ( 45 miles per hour ) above the Pacific Ocean, hoping to pick up a fast Subtropical jet stream over Hawaii by Tuesday.

The Swiss-English team, which had been traveling straight from west to east for days, Saturday changed direction somewhat toward the southeast to get into position to catch the Subtropical jet stream south of Hawaii by Monday or Tuesday.

Continuing across the southern tier of the United States, the subtropical jet stream this week has conveyed one of the California storms into the Gulf Coast states, where it is now helping pump abnormally warm air into the Northeast.
