Forecasting the weather is of course important for anyone planning a trip in his yacht. Many factors enter into the problem of making successful weather forecasts from the examination of weather maps.预测天气当然是重要的人计划在他的行程游艇。许多因素进入问题的决策成功的天气预报从检查的天气图。 The experienced forecaster, for example, has due regard for the area under consideration, the topography of the land, and the distribution and effect of land and water areas. Professional forecasters, from long experience, have found however that certain general conclusions may be drawn which are of help in analyzing probable changes in the weather map.经验丰富的预报，例如，已充分考虑该地区正在审议中，地形的土地，分配和作用的土地和水资源的地区。专业人员预测，来自长期的经验，但已经发现，某些一般性的结论可得出这是帮助分析可能天气变化的地图。 Some of the more important ones are summarized in the Weather Bureau's publication, Weather Forecasting, as follows: 1.一些更重要的概述了气象局的出版，气象预报，内容如下： 1 。 When there is an area of high pressure over the southeast and a cold wave in the northwest threatens, there will be storm development in the southwest and precipitation will be general. 2.当有一个地区高压东南和冷波在西北威胁，将有风暴的发展在西南和降水将普遍。 2 。 If a storm forms in the southwest and is forced to the left of a normal track, another storm will immediately begin to develop in the southwest and it becomes a sure rain producer.如果一个风暴的形式在西南部，是被迫的左侧正常的轨道上来，另一场风暴将立即开始开发西南，它成为一个确保雨生产者。 Storms that develop in the southwest and move normally are quickly followed by clearing weather. 3.暴风雨开发西南和移动通常是紧接着结算天气。 3 。 Troughs of low pressure moving from the west are of two types: the narrow and the wide.低压槽影响从西部分为两类：狭义和广泛。 The former moves eastward slowly and storm centers develop in the extreme northern and the extreme southern ends.前向东移动缓慢，风暴中心发展的极端北部和南部的极端目的。 When the trough is wide the development of an extensive storm area is not uncommon, especially if the wide intervening area between the Highs shows relatively high temperatures. 4.当槽广泛的发展广泛的风暴区的情况并不少见，尤其是如果广泛干预之间的地区最高显示相对较高的温度。 4 。 When the northern end of a trough moves eastward faster than the southern end the weather conditions in the south and southwest remain unsettled and the chances are that a storm will form southwest of the High that follows.当北端槽向东移动速度比南端的天气状况在南部和西南部的尚未解决的机会，一个风暴将形成西南高，如下。 When the southern end moves faster than the northern end settled weather follows. 5.当南端移动速度比北端解决天气如下。 5 。 Storms that start in the northwest and move southeastward do not gather great intensity until they begin to recurve to the northward.风暴开始在西北和东南移动不收集大强度，直到他们开始recurve对北上。 At the time of recurving they move slowly, as a rule, and care must be exercised in predicting clearing weather. 6.当时recurving移动缓慢，作为一项规则，和照顾的行使必须清除的天气预测。 6 。 Marked changes in temperature in the southeast and northwest quadrants imply an increase in the storm's intensity.显着的变化温度在东南和西北象限意味着增加了风暴的强度。 Small temperature changes do not indicate a further development of the storm. 7.小温度的变化并不表明进一步发展的风暴。 7 。 Abnormally high temperatures northwest of a storm indicate that it will either retrograde or remain stationary. 8.异常高温西北风暴表明，它要么逆行或保持平稳。 8 。 East of the Rocky Mountains a storm which moves to the left of its normal track increases in intensity. 9.东亚的洛基山脉风暴而采取行动的左侧其正常发展的轨道增加强度。 9 。 Storms with isobars closely crowded on the west and north west generally move slowly and to the east or southeast, and the precipitation and high winds are maintained unusually long in the northern and western quadrants. 10.沙尘暴与共振态密切拥挤的西部和西北部普遍缓慢和以东或东南，以及降水和强风维持超长的北部和西部象限。 10 。 Storms with the isobars closely crowded in the south and southeast quadrants move rapidly northeastward, and the weather quickly clears after the passage of the storm center. Systems of communication throughout the country are today so highly developed that, through the medium of newspapers, the telegraph, telephone, radio and even the radiotelephone, yachtsmen are generally able to avail themselves of the scientific weather information and forecasts issued by the United States Weather Bureau, rather than being forced to rely on their own doubtful capacity to predict by means of local observations.沙尘暴的共振态密切拥挤在南部和东南部象限迅速向东北，以及天气迅速清除后通过的风暴中心。通信系统在全国各地今天这样高度发达，通过媒介，报纸，电报，电话，收音机，甚至无线电话，游艇驾驶员一般都能够利用的科学气象信息和预报发布的美国气象局，而不是被迫依靠自身的能力令人怀疑的预测手段的地方的意见。 (Of course, during a war such systems of weather communications are suspended.) Taking note of some of the predictions above will make your life as a yachtsman so much easier. （当然，在战争等天气系统的通信中断。 ）注意到一些上述预测将让您的生活作为帆船运动员，以便容易得多。
