数学建模仿真教程-2.2 作业

项目2.2雨量预报（活页）仿真练习题【问题描述】在雨量预报问题中，在位于8×6的网格点上进行雨量预报，已知某日3点至9点（6小时）用两种不同方法预报的雨量如表2.2所示，雨量用毫米做单位，小于0.1毫米视为无雨，这些预报点的经纬度如表2.3所示。同时设立6个观测站点测量实际雨量。同日同时段的实测数据如表2.4所示。二维码数据2.3请使用数学建模方法研究以下问题：建立科学评价两种二维码数据2.3（本题来自全国大学生数学建模竞赛2005年C题）表2.2预报雨量方法一9.18949.90457.51436.30455.70045.426410.490313.02567.29765.66494.90345.052913.421715.91464.07816.54391.39154.870712.22069.53765.69648.16813.78564.990314.259835.407616.272510.05185.80185.27538.13665.51963.91862.6145.60555.54075.75221.39060.78934.51995.20585.45965.41243.66242.35874.52725.08745.1781方法二10.06668.59497.57166.1345.15185.026910.724814.32266.99136.3885.27215.24912.518316.83694.07468.20121.48914.941212.906810.74555.31276.96924.01694.873215.001831.337917.17919.78046.39295.13928.92575.78823.84842.44795.0495.32286.07831.40090.82014.40334.92475.55915.6523.37862.4934.60744.83675.063表2.3预报点的经纬度纬度经度28.528.528.428.428.328.2117.7118.7119.8120.9121.912329.329.329.229.229.129117.7118.8119.9120.9122123.130.130.1303029.929.8117.7118.8119.9121122.1123.230.930.930.830.830.730.6117.8118.9120121.1122.2123.331.731.731.731.631.531.4117.8118.9120121.1122.3123.432.632.532.532.432.332.2117.8119120.1121.2122.3123.533.433.333.333.233.133117.9119120.2121.3122.4123.634.234.234.1343433.9117.9119.1120.2121.4122.5123.7表2.4实测点的数据站号123456纬度32.3831.4331.6231.1330.229.78经度120.6119.5121.5119.2120.3118.2雨量0.816.91.70.10.120.9步骤一，模型假设步
