Both VEGA balloons encountered vertical winds with typical velocities of 1 to 2 meters per second. These values are consistent with those estimated from mixing length theory of thermal convection. However, small-scale temperature fluctuations for each balloon were sometimes larger than predicted. The approximate 6.5-kelvin difference in temperature consistently seen between VEGA-1 and VEGA-2 is probably due to synoptic or planetary-scale nonaxisymmetric disturbances that propagate westward with respect to the planet. There is also evidence from Doppler data for the existence of solar-fixed nonaxisymmetric motions that may be thermal tides. Surface topography may influence atmospheric motions experienced by the VEGA-2 balloon.
两个 VEGA 气球都遇到了典型速度为每秒 1 到 2 米的垂直风。这些值与热对流混合长度理论估计的值一致。然而，每个气球的小尺度温度波动有时比预测的要大。VEGA-1 和 VEGA-2 之间始终存在约 6.5 开尔文的温差，这可能是由于相对于行星向西传播的天气或行星尺度非轴对称干扰造成的。多普勒数据还表明存在可能是热潮汐的太阳固定非轴对称运动。地表地形可能会影响 VEGA-2 气球所经历的大气运动。
