一、前言卫星云图比较直观,而且不受地形、国界等客观条件的限制,在大范围的天气预报中发挥着越来越明显的作用。但是,云图接收设备比较昂贵,又需要较高技术水平的接收、维修人员,依我们现有的经济条件,这一技术还不能在基层台站得到普及。随着气象传真业务的广泛开展,我国早期推广应用的114传真发片机、117传真收片机正逐步被新一代传真设备所代替。但目前
I. INTRODUCTION Satellite imagery is more intuitive and is not subject to any objective conditions such as topography or national boundaries. It plays an increasingly significant role in a wide range of weather forecasts. However, the cloud receiving equipment is expensive and requires high-level receiving and maintenance personnel, which, according to our current economic conditions, can not yet be popularized at the grassroots stations. With the extensive development of meteorological facsimile services, China’s early introduction of 114 fax hair machine, 117 fax machine is being gradually replaced by a new generation of fax equipment.
