Importance of World Meteorological Day 2020

World Meteorological Day 2020

World Meteorological day is annually celebrated on 23 march by World meteorological organization. World Meteorological day commemorates the coming into force on 23 March 1950 of the Convention establishing the World Meteorological Organization.

World Meteorological organization showcases the essential contribution of National Meteorological and Hydro logical Services to help the society. 

The theme of World Meteorological Day is chosen based upon the climate, weather or water related issues around the world.

This year , World Meteorological Day 2020 theme is chosen as climate and water. As we have published in our post about World Water day 2020 theme, which is also focused on water and Climate as "Count Every drop".

As we talk about our previous post Save Water Save Life, the concern is about fresh water availability.

Fresh water is limited and human cannot survive without water more than three days. Water is the main element for our food, industries and all goods and services. 

So the world is going to face a new increasing challenges poses by water stress, drought and flood , which leads to lack of access to clean water.

Now the question is how World Meteorological Organization can help in Water scarcity ?

So Water scarcity can be reduced by getting   improved  forecasting, monitoring and management of water supply with help of correct meteorological services.

World Meteorological day 2020 theme is focused on the count every drop, frozen water , drought, flood , Evry drop counts and water and climate change.

Count every drop

World meteorological day
Count every drop is meant by collection of water data and models to frame effective polices for flood and drought management. Assessment of water resources will help us to improve the water efficiency. 

Frozen Water 

Frozen water
As we all know that most of the rivers are originates from the frozen mountains. Frozen water is the main source of fresh water for large population of world. 

But increasing global warming and it's effect, it is reducing day by day. The current rate of global mean sea level rise is 5 mm/year correspond to water discharged by amazon river in about 3 month.

So with help of GIS and remote sensing technology, we can prepare a data base to analysis of climate change effect.

Drought

A prolong dry period in the nature climatic cycle is called drought. Drought can be due to low rain fall, over exploitation of water resources and inappropriate land use.

Drought has an major impact on food security, health and population migration.So WMO can help to control drought by improved data analysis and framework of policies on climate change.

Floods

Floods are the deadliest natural hazard which effect most the world population every year. The trend of flood damages has been increased in during the last decade.

Flood damages  are the consequences  of increasing heavy precipitation, change in upstream land use and increasing concentration of population in flood prone area.

So there is need for adequate flood planning and management to reduce the lossess.

20 million people are at risk from flooding with the associated damage costing nearly US$80 billion.

World Meteorological organization take an initiatives as Associated program on flood management and Flash flood guidance system.

Climate change and water

Climate change is leading the change in hydrological cycle to speed up the rise in temperature which results in increase in rate of evaporation. More evaporation means more precipitation, but the distribution is irregular. 

Irregular distribution of precipitation leads to flood in some area while drought in some area around the world.

So WMO helps to identify the rate of precipitation and its distribution around the world with analysis of meteorological data on climate and surface water.

Every Drop Count

If we look at the fact, only 0.5% of the Earth’s water is readily available for human consumption and around 40 % people are affected by water scarcity.

So there is need to focus on sustainable development around the world to meet the future need of increasing population.

WMO support  the sustainable development with covering information of hydrological cycle.
