A kind of container of determining barometric gradient and ultrasound data, including obtain ultrasound data and generate velocity vector distribution inflow container and ultrasound data. This method further comprises calculating to accelerate and velocity vector distribution map. The acceleration includes accelerating at least one time, and calculating time acceleration includes reducing noise to determine that the time accelerates to subtract miscellaneous speed data from above-mentioned from above-mentioned velocity vector profile. This method further comprises determining barometric gradient and acceleration calculated. This method further comprises the container for showing ultrasound image, and there is label to indicate that barometric gradient is superposed thereon.
