Biomass of the two trees namely Azadirachta indica (Neem) and (Jalpai) Alaerocarpus serratus is measured which were uprooted in the last November by the ravaged cyclone Bulbul, the ratio between Above Ground Biomass (AGB) and Below Ground Biomass (BGB) of both the trees of the Tropical Dry Deciduous Forests type is about 20:1, root systems of both the trees are not at all sufficient to erect or support this relatively higher mass of stem, branch, and leaves particularly during the cyclonic storms, do the rest of the trees have the same root systems, is this low quantitative root systems responsible for the low content of Below Ground Biomass of the Tropical Dry Deciduous Forests type whereas the BGB is relatively more in the other forest floors like temperate or conifers
You should look at components of below ground biomass. To start with look at root biomass, length & other atributes, then the soil type & structure and optimum moisture etc ... leaf area (index) & wind speed interactions. Whole organism models need other details to understand the 'system' you need to quantify...
Whether the surrounding soil is to be incorporated during quantifying Below Ground Biomass attributed by the root system of a tree
Brij M Upreti - convey my thanks for the link related to the ratio of AGB/BGB
Just yesterday I have checked, observed and studied the uprooted trees for the super cyclone Amphan in 9 forest patches of Tropical Dry Deciduous Forests types in 3 districts of West Bengal that revealed the area, volume, and the mass of the root systems is more than 20 times less than that of the above ground portion of the trees of the heights ranging between 30 - 45 ft height, and DBH 1 ft to 12 feet, if it's possible to attached the photographs of those uprooted trees with the entire stem including branches and the complete exposed root systems attached to the stem, then it will be possible to check visually for all.
This is more likely to occur when soils are wet and the tree's roots are unable to securely anchor themselves in the soil.

Gonfa Kewessa- almost 60 trees of a community forest are uprooted by the devastating strong winds by the Super Cyclonic storm Amphan
