* Duration of **isolation is long** * Intensity of **sunshine is high** * The **land absorbs heat faster** than the sea => **hot air rises** => form a **low-pressure area** * The **sea has lower temperature** => the **air to sink** => form a **high-pressure area** * **Wind blows from high pressure area to low pressure area** => form **SE and SW monsoons**
40
How are monsoons formed in the **Winter**? ## Footnote *2.3 Why are the water resources in China distributed in such a way*
* Duration of **isolation is short** * Intensity of **sunshine is low** * The **land loses heat faster** than the sea => **cold air sink** => form a **high-pressure area**. * The **sea has high temperature** => the **air to rise** => form a **low-pressure area**. * **Winds blows from high pressure area to low pressure area** => form **NW monsoons**
41
