风云全球瞰这里「印度洋热带气旋“弗雷迪”」

2月22日00:00（世界时，下同），南印度洋热带气旋 “弗雷迪”的中心位于马达加斯加境内（北纬21.3度，东经47.0度）， 中心附近最大风力达到28米/秒，中心气压985 hPa。

The center of tropical cyclone “FREDDY” was located at 21.3°S, 47.0°E,  at 00:00 (UTC, hereinafter same) on February 22. It had a maximum wind speed of 28 m/s and a minimum pressure of 985 hPa near the center of the cyclone.

登陆后强度迅速减弱，气旋眼区较模糊。FY-4A气象卫星云图（图1）显示，08时“弗雷迪”具有较清晰的螺旋结构，随登陆强度减弱，螺旋结构逐渐松散。

The cloud map of FY-4A (Fig. 1) meteorological satellite shows “FREDDY” has landed on Madagascar, and it still has an obvious spiral structure.

FY-4A气象卫星红外增强动画（图2）和云顶高度动画显示（图3），08时“弗雷迪”气旋中心云顶温度低于-70 ℃，云顶高度达到18km以上，随强度减弱，气旋中心云顶温度上升、云顶高度下降，云顶温度低于-70 ℃、云顶高度大于18km区域逐渐缩小。

The Infrared enhanced cloud animation of FY-4A (Fig. 2) meteorological satellite shows the cloud top brightness temperature of the circulation center is below -70℃, and the cloud top height of the circulation center is higher than 18km (Fig. 3).

“弗雷迪”预计将以每小时30-35公里的速度向西南移动，但强度将会减弱。

The “FREDDY” is expected to move southwest at the speed of 30-35 kilometers per hour, with the strength weakened.
