气象人员解释说:虽然有了卫星、雷达和大型计算机辅助,但天气预报仍然有时不准。这是因为影响大气变化的因素太多,而且其物理机制异常复杂,现有的科学水平还难以解释风云变幻的全部奥妙;另外,大气探测手段还不十分先进。目前,我国地面观测网点稀疏,内地虽然较多,但山区、高原、 Meteorologists explained that although satellites, radar, and large computer aids are available, weather forecasts are still sometimes inaccurate. This is because there are too many factors that affect the atmospheric changes, and its physical mechanism is extremely complex. The current scientific level is still difficult to explain all the mysteries of the ever-changing atmosphere; in addition, the atmospheric detection methods are not yet very advanced. At present, China’s ground observation sites are sparse, although there are many inland areas, but mountainous areas, highlands,
