Abstract
A method for predicting the horizontal drift of a marine meteorological sounding balloon comprises calculating the rising speed of a sounding balloon in dry air; taking the sounding balloon release point as the coordinate origin at time 0; obtaining the wind speed at the coordinate origin using grid point data and the logarithmic law of average wind, performing vector synthesis with the rising speed, and calculating the coordinates of the sounding balloon 30 seconds after the sounding balloon; taking the coordinates of the last 30 seconds as the new coordinate origin, and so on until the sounding balloon enters the free atmosphere; then obtaining the wind speed using linear interpolation, performing vector synthesis with the rising speed, and calculating the coordinates of the sounding balloon 30 seconds after the sounding balloon until the sounding balloon enters the stratosphere; then obtaining the horizontal wind speed using linear interpolation, performing vector synthesis with the rising speed, and calculating the coordinates of the sounding balloon 30 seconds after the sounding balloon; and so on until the balloon flies out of the stratosphere, thereby obtaining the flight trajectory of the sounding balloon. The present invention can provide a reference for the detection of target weather phenomena at sea, which is beneficial to reducing the detection cost and improving the pertinence and accuracy of the detection.
