Rivers carry the living impressions of civilisations that have settled on their banks since the dawn of time, are home for unique flora and fauna. How can we better understand and protect them? #Vigilife has launched the #30sentinelrivers program with #eDNA. A thread 1/n ImageImage
By building an international network of partners and sharing #eDNA know-how, #Vigilife is establishing long term #monitoring programs, which will become a precious tool for safeguarding freshwater biodiversity.
1. The #Amazon: born out of the drying up of an inland sea, I am one of the longest rivers in the world. Together with my tributaries, I contain nearly 20% of the #biodiversity of all the rivers on earth and play an essential role in the global water cycle. Image

Congratulations to Ethiopia and Ethiopians everywhere on today's completion of the 2nd filling of the #GERD. It has been a great honour to follow along during this moment.

Today's rainfall forecasts for #NorthAfrica, #HornOfAfrica and #MiddleEast follow.
In honour of the #GERD we will change up the order of today's bulletin and get right to the most important issue, rain over the #Abbay basin, which due to its great quantity and consistency made this possible over such a short time period.
But first a brief explanation, as when it comes to the GERD not all rainfall counts. The first image here shows the path of the #BlueNile / #Abbay from Lake Tana to Khartoum where it meets the White Nile and becomes "The Nile".

The convective storms over Ethiopia and Sudanese Nile Basins tonight is remarkably intense. Bringing massive amounts of rain across a huge area, including the #Abbay /#BlueNile basin, on the 4th day of #GERD filling.

Today's #HOA #ME and #NorthAfrica rainfall forecasts follow.
In this wider view you can see the full size of today's rain areas which extended deep into Sudan later in the afternoon.
These two images are at sunset the sizes of the two large convective areas, the eastern one extends well north into Eritrea and covers Tigray and the entire #Abbay Basin. The first image provides an idea of size. Each storm area is larger than the UK and Ireland.

Day three of official #GERD filling today in Ethiopia. And a gap in the clouds this morning reveals the GERD lake on the #Abbay river.

Today's #HornOfAfrica, #NorthAfrica and #MiddleEast rainfall forecasts follow.
Here we zoom out a little, the source of the #Abbay/#BlueNile Lake Tana takes pride of place. You can see the #GERD lake in the bottom left hand corner.

These images are from the @NASA Modis Worldview service. Also below a picture of the #GERD from back in January.
Here's today's big picture as ever of the great Sahara Desert. You can see today's #ArabianStorms starting up bottom right, and top left a new rain front coming into Western Europe where the 2021 #EuropeBigWet continues to bring rain and unseasonably mild temperatures.

Today's #NorthAfrica and #HornOfAfrica forecasts follow.

Below a satellite picture this morning with all the Nile basins including the #Abbay/#BlueNile in #Ethiopia (where it passes through the #GERD) + White Nile, #Sudan, #SouthSudan, #Uganda & the states around Lake Victoria.
10 day rainfall forecasts from the CMC, KMA, GFS and ECMWF models for June 9th through 19th.
A few animations. This one is connected to the separate tweet threads about #EuropeBigWet, which appear to be being driven by Jets of wet air coming off the Atlantic and crossing the Sahara into Europe.

This animation shows a jet crossing Libya and pumping water into Georgia.

Today's Rainfall Forecasts for the #HornOfAfrica and #MiddleEast follow in this thread.

Below you see the Ethiopian Highlands from this morning and including most of the #BlueNile #GERD #Abay watershed . The large storm on the left is mostly over Sudan. On the RHS is #Lalibela.
Here you see an animation of the storm starting up this morning.
This satellite image (@NASA Modis ) shows the area in the Arabian Sea which computer models indicate could generate two cyclones in coming days. You can see the latest GFS forecast runs for those cyclones in the attached thread.

The Horn of Africa this morning @NASA worldview, got a great view and more pictures will be included in today's rainfall forecast thread for #Ethiopia #HoA and the #MiddleEast.

Today's forecasts follow.
Here's the first. A view mostly of #Sudan, capturing both the #WhiteNile and #BlueNile as well as part of the Nile below Sudan on its way to Egypt. On the right hand side Lake Tana can be seen through the clouds.

If you look very carefully you may be able to see #GERD.
This view which captures the area below that in the previous image has borders on it to make it easier to see where the abundant green in the firsy image in this thread is located. The rains of the past few weeks appear to be doing God's work in the region.

An image of thunderstorm activity in the Ethiopian #Abbay #BlueNile basin this afternoon, also showing significant rains South #Yemen and over most of #Somalia.

Todays, 27th April, accumulated rain forecasts for the #MiddleEast & #HornOfAfrica follow in the thread below.
#ArabianStorms activity was boosted today by moisture flowing from the #Ethiopian monsoon rains in the Ethiopian Highlands, the watershed of the #Abbay #BlueNile catchment.

Below you see a 10-day GFS forecast of accumulated rain over North Africa.
This animation shows the flows of moisture from this morning across the Red Sea. A process which is called the "Southern Gate" by Saudi weather entusiasts. #ArabianStorms #Abbay #BlueNile #GERD

Ethiopia forecast rainfall update: 21st April 2021

GFS, KMA and ECMWF Model forecasts - all 10 days.

NOTE: There is a significant increase in expected rain over the 10 day period compared to forecasts from earlier in April.
Here is an animation from this afternoon of rain cloud formation over the Blue Nile Basin today. It is picking up speed.
And here is an animation of an explosive burst of convection south of Mogidishu in Somalia. In 5 hours the storm had grown to be larger than the island of Ireland.

(1/22) Our new paper @NatureEnergyJnl (rdcu.be/cikbq) proposes a solution to break the deadlock in negotiations between #Ethiopia ๐Ÿ‡ช๐Ÿ‡น, #Sudan ๐Ÿ‡ธ๐Ÿ‡ฉ & #Egypt ๐Ÿ‡ช๐Ÿ‡ฌ on the Grand Ethiopian Renaissance Dam (#GERD) on the #BlueNile โ€“ with help of #solar and #wind power. Thread๐Ÿ‘‡ Image
(2/22) The #BlueNile (Abay) is highly seasonal, with extreme differences in flow between dry and wet months. #GERDโ€™s reservoir is so large it can store the full annual flow & deliver #hydropower at a stable rate throughout the year - suppressing the river flow #seasonality. Image
(3/22) Delivering hydropower w/o seasonality makes loads of sense from Ethiopian perspective, but overhauls natural timing of water reaching #Sudan & #Egypt. Behind many disagreements on #GERD lies downstream countriesโ€™ fear of s/o upstream having control over #BlueNile flowโ€ฆ Image
