Typically, La Niña results in less disruptive winds, known as wind shear, making conditions prime for tropical development across the Atlantic. However, La Niña has yet to officially develop.
Wind shear acts to tear developing storms and hurricanes apart before they can get organized. Unrelenting heat: Phoenix hits 100 degrees for the 100th day in a row Atlantic storm tracker
Wind shear is stiff breezes that can prevent a tropical storm from forming or cause a tropical storm or hurricane to weaken. When wind shear is low, it makes it easier for a tropical storm to form ...
Vertical wind shear forces the rainfall pattern around a tropical cyclone to become highly asymmetric, with most of the precipitation falling to the left and downwind of the shear vector, or downshear left. In other words, southwesterly shear forces the bulk of the rainfall north-northeast of the center. [9]
Wind shear could play key role Two conditions that have played a role throughout this hurricane season could allow yet another depression or tropical storm or even a hurricane to form: low wind ...
Tropical cyclone forecasting is the science of forecasting where a tropical cyclone's center, and its effects, are expected to be at some point in the future. There are several elements to tropical cyclone forecasting: track forecasting, intensity forecasting, rainfall forecasting, storm surge, tornado, and seasonal forecasting.
As a result he had "no choice but to forecast weakening again and again." [9] Bursts of convection continued to keep the storm alive in the face of moderate upper-level wind shear. [10] On January 2, Zeta began to gradually intensify "against all odds and forecasts". [11] Convection remained over the center, and the storm's outflow expanded as ...
An upper-level trough in the atmosphere is expected to continue bringing near-normal to above-normal wind shear over the tropical Atlantic and Caribbean, the forecasters said.
