印度降雨量分布
印度的正常年降雨量约为 125 厘米,但它具有令人难以置信的空间变化。印度在地质方面是一个幅员辽阔的国家,不同的地区遇到完全不同的气候环境。这同样反映在印度降雨的分散上。一些地区的降水量极高,而另一些地区则分布极少。印度最值得注意和最不重要的区别是大约 1178 厘米。印度全年的降雨量难以预测,全国大部分地区的明显暴风雨季节从 6 月左右开始,到 9 月结束。
- 西海岸和印度东北部的部分地区每年降雨量超过 400 厘米。
- 拉贾斯坦邦西部和连接古吉拉特邦、哈里亚纳邦和
旁遮普邦。 - 德干级别内部和 Sahyadri 以东的降雨量较低。
- 降雪仅限于喜马拉雅地区。
- 年降水量是一年到另一年的特殊因素。
- 印度的降雨分布不均。除了分布不均外,年降水量也变化很大。
Climate is the normal climate in a spot over numerous years. While the weather conditions can change in only a couple of hours, the environment requires hundreds, thousands, even a large number of years to change.
印度各地区年降雨量分布如下图:
- 从加尔各答到阿姆利则,降雨量逐渐减少。
- 它显示了从德干级别的海滨地区向内下降的模式。
- 东北部地区的降雨量比印度西北部地区多。
根据气象/气候部门的年度信息,印度的正常降雨量为120 厘米。印度的降雨区域分类如下,印度有四个降雨区域如下
Areas of Inadequate Rainfall in India
Andhra Pradesh, Karnataka and Maharashtra, Ladakh, and a large portion of western Rajasthan get rainfall below 50 cm. Jaisalmer in Rajasthan is the spot in India that gets the least rainfall.
Low Rainfall Areas in India
Maharashtra, Gujarat, Karnataka, Tamil Nadu, Andhra Pradesh, Madhya Pradesh, Punjab, Haryana, and Western Uttar Pradesh are regions having 50 to 100 cm of rainfall.
Medium Rainfall Areas in India
Gujarat, east Tamil Nadu, northeastern Peninsula covering Odisha, Jharkhand, Bihar, eastern Madhya Pradesh, northern Ganga plain along the sub-Himalayas, and the Sachar Valley and Manipur, Rainfall between 100-200 cm.
Areas of high rainfall in India
The most noteworthy rainfall happens along the west coast, on the Western Ghats, as well as in the sub-Himalayan regions in the upper east and the slopes of Meghalaya. Northeastern locales and the windward side of the Western Ghats experience a normal 400 cm of yearly rainfall. In the Brahmaputra valley and the connecting slopes, the rainfall is less than 200 cm.
The areas encountering 200-300 cm rainfalls have a place within this zone. Eastern India majorly covers this zone.
归因于暴风雨的概念,每年的降雨量在一年到另一年的情况下非常重要。在拉贾斯坦邦、古吉拉特邦和西高止山脉的背风侧等降雨量少的地区,波动很大。印度的降雨分布受到塔尔沙漠和喜马拉雅山脉的影响。印度洋、阿拉伯海、孟加拉湾和太平洋南部地区的温度和压力变化同样是该国季风倾盆大雨的关键部分。
示例问题
问题 1:印度哪个地区的降雨量为 400 厘米?
回答:
Mawsynram town of Meghalaya gets rainfall over 400cm. Northeastern districts and the windward side of the Western Ghats experience a normal of 400cm of yearly precipitation. Regions like Assam, Meghalaya, Arunachal Pradesh and sloping lots of the Western Ghats are host to tropical rainforests.
问题2:解释印度降雨区的分布,并简要解释其中一个?
回答:
The average annual rainfall in India is 120 cm and the rainfall regions in India are classified in 4 regions
- Low rainfall region.
- Inadequate rainfall region
- Medium rainfall region.
- High rainfall region.
Medium Rainfall Region
Gujarat, east Tamil Nadu, northeastern Peninsula covering Odisha, Jharkhand, Bihar, eastern Madhya Pradesh, northern Ganga plain along the sub-Himalayas, and the Sachar Valley and Manipur, Rainfall between 100-200 cm.
问题 3:描述印度的降雨类型。
回答:
Rainfalls are classified into three main types based on Origin, they are
Convectional rainfall, Orographic or relief rainfall, Cyclonic or frontal rainfall. And another rainfalls are classified in three types based on Intensity, they are
- Low rainfall – rate of rain is b/w 0 to 2.5 mm
- Moderate rainfall – rate of rainfall is b/w 2.6 mm to 7.6 mm
- Heavy rainfall – the rate of rainfall is above 7.6 mm
问题四:为什么印度会出现降雨分布?
回答:
The rainfall distribution in India will occur due to these reasons stated below
- The Bay of Bengal some portion of the South-West storm brings downpour.
- Distance from the Sea: Areas along the coast get more rainfall when contrasted with those areas which further away from the ocean.
- Wind Direction: Due to the Arabian Sea Branch blowing corresponding to the Aravalli Hills, Rajasthan gets inadequate rainfall.
问题5:解释印度的季风类型并解释。
回答:
In India the monsoons are classified into two types
- Southwest monsoons
- Northeast monsoons
Southwest monsoons
The Southwest monsoons are the primary monsoon, roll in from the ocean and fires advancing up India’s west coast toward the beginning of June. By mid-July, the greater part of the nation is shrouded in downpour. This progressively begins clearing from most places in northwest India by October.
Northeast monsoons
The northeast monsoons influences India’s east coast during November and December. It’s a short however extraordinary storm. The provinces of Tamil Nadu, Karnataka, and Kerala get the greater part of their rainfall from the upper east storm, while the remainder of the nation gets the majority of its rainfall from the southwest rainstorm.
