Episode Details

Northern China is entering its most critical flood-control period, with meteorologists warning that an early rainy season and increasingly volatile weather patterns could heighten the risk of severe flooding in the weeks ahead.

我国北方已进入防汛关键期，气象专家提醒，汛期提前、天气形势愈发多变，未来数周发生严重洪涝灾害的风险将有所上升。

The rainy season in North China officially began on July 10, eight days earlier than the long-term average, according to the National Climate Center.

国家气候中心数据显示，华北地区7月10日正式入汛，较常年平均时间提前8天。

"The rainy season this year has arrived both early and with remarkable intensity," said Chen Lijuan, chief forecaster at the center.

国家气候中心首席预报员陈丽娟表示：“今年汛期不仅来得早，降雨强度也十分突出。”

She said an active Northeast China cold vortex — a persistent upper-level weather system that often triggers prolonged rainfall — has contributed to unusually heavy precipitation across northeastern and northern China since June.

她介绍，东北冷涡活动频繁，这一持久的高空天气系统极易引发持续性降雨，自6月以来，我国东北、华北地区降水便异常偏多。

The rainy season in Northeast China began on June 4, nine days earlier than average. Since June 1, rainfall has been well above normal across most of the region and North China.

东北6月4日入汛，较常年提前9天。6月1日至今，东北大部、华北地区降雨量均显著高于常年均值。

The early onset follows months of exceptionally heavy rainfall that have already left much of the region saturated before the traditional peak flood season.

早在主汛期来临前，连续数月的强降雨已让北方大部分区域土壤含水量趋于饱和，如今汛期再度提前到来。

From April 1 to July 12, average precipitation across northern China reached 228.6 millimeters, 23.1 percent above the long-term average and the highest for the same period in the past decade, the center said.

国家气候中心称，4月1日至7月12日，北方地区平均降水量达228.6毫米，较常年同期偏多23.1%，
