2.1地形条件

第2章 设计资料

盘锦市二界沟渔港位于辽东湾北部，辽河口与双台子河口之间的海岸线，地理坐标东经121°57′20″，北纬40°48′30″.

2.2气象条件

（1）气温 年平均气温 8.6℃

月平均最高气温 28.1℃， 出现在7月份 月平均最低气温 -14.7℃，出现在1月份 极端最高气温 35℃（1955年7月25日） 极端最低气温 -29.3℃（1964年2月3日） （2）降水

本地区集中降水月份为7~8月份

年平均降水量 645.3mm

年最大降水量 985.0mm（1995年） 年最小降水量 364.2mm（1978年） 一日最大降水量 219.3mm（1957年） （3）风况

本港区风况呈季节性变化，每年4月5月风速较大，平均风速5.5米每秒，8月9月风速较小，风俗一般在3.4米每秒左右。

历史该地区台风发生的次数较少，每次风力在7级到8级，最大风速为26.0,米每秒。 本地区多年各向最大风速及风向频率分布情况见表1，据此绘出最大风速及风向频率玫瑰图。由玫瑰图可知，本地区常风向为SSW、NNE，强风向为SSW、NNE、NE、SE。结合港区地形图，可确定本港常风向与强风向均为SSW。

（4）冰清

本港平均结冰日数为90天，结冰初日为11月末，消冰日为翌年3月初。结冰期港内渔船基本上坞。无渔船作业。

（5）雾况

本港历年平均雾日为14.5日，月平均雾日为1.2天。雾持续最长时间为2天，大多数在一天左右

（6）相对湿度 平均相对湿度 66%

每年7月8月相随湿度较高，可达80%~81% 每年的2月3月相对湿度较低，在56%~57%左右。

2.3水文条件

（1）潮汐和海流

本区潮汐类型为不规则半日潮型，多年平均潮差为2.64米，最大潮差为4.40米。平均涨潮历时4小时28分，平均落潮历时7小时16分。

?本港各种特征潮位

最高潮位 5.19m 最低潮位 - 0.44m 平均高潮位 3.23m 平均低潮位 0.51m ?设计水位

设计高水位 4.2m 设计低水位 0.1m 极端高水位 5.15m 极端低水位 -1.40m

以上各种高程基准面均为营口地区高潮基准面，该基准面在黄海基准面一下
