matlab地球投影上画风应力旋度代码

以下是在地球投影上画风应力旋度的 MATLAB 代码示例：

%% Load wind data
load('wind.mat'); % Load wind data

%% Compute curl of wind data
[dx, dy] = gradient(u);
[dzdx, ~] = gradient(v);
[~, dzdy] = gradient(w);
curl = dzdy - dy;

%% Generate Earth projection
load('topo.mat', 'topo', 'topomap1');
axesm('mollweid', 'Frame', 'off', 'Grid', 'off');
axis off;
gridm off;
framem off;
load coastlines;
geoshow(coastlat, coastlon, 'DisplayType', 'line', 'Color', 'black', 'LineWidth', 1);

%% Plot curl data on Earth projection
colormap(flipud(topomap1));
pcolorm(lat, lon, curl);
shading interp;
colorbar;

%% Add title and labels
title('Curl of Wind Data on Earth Projection');
xlabel('Longitude');
ylabel('Latitude');
