In the 21st century,clouds and stormy weather no longer automatically bring military operations to a halt or force a change in targets. Techonologies such as the Global Positioning System now 1 cruise missiles (巡航导弹) and other smart weapons to home in on (瞄准并飞速接近) their targets. But the weather still is a factor that must be 2 with, especially with precision-guided weapons that must be 3 accurate to be effective. Fortunately, the ability to obtain weather 4 will get better. In the next few years. remote weather sensors will grow 5 on unmanned vehicles. This will create a network of observing platforms that will give commanders a(n) 6 overview of weather in the battle zone. In some areas you'll have direct 7 of weather information straight from the computers to black boxes in aircraft and othe vehicles. That will be especially important for target-bound aircraft. Such technology will give whoever possess it a tremendous edge (优势) over their enemy and enable them to use developing weather conditions to their 8 . As we get superior satellites into space, we'll gain huge advantages in 9 meteorological conditions in denied areas, where we don't have people on the ground. And our modeling ability will continue to improve as our computers get more 10 . The past 10 years have witnessed a revolution in our communications and computer abilities. It's exciting to think of what the next 10 years will bring.
