The get stream is generated due to the difference in temperature between the equator and poles. The equator mostly stays the same temperature year-round. In the summer hemisphere, the pole is relatively warm (due to continuous sunlight), and the jet stream is weak because the temperature difference is smaller. In the winter hemisphere, the pole is relatively cold (due to perpetual darkness), and so the difference in temperature is relatively large. Thus, the jet stream is faster in the winter. The technical term for this phenomenon is “thermal wind balance”.
