HRRR(High-Resolution Rapid Refresh)

High-Resolution: HRRR is a high-resolution weather model, meaning it operates on a fine spatial grid to capture detailed weather patterns. Specifically, it uses a 3-km horizontal resolution, allowing it to resolve smaller-scale phenomena like thunderstorms or local wind patterns that coarser models (e.g., GFS at 0.25-degree resolution) might miss.

Rapid Refresh: HRRR is updated frequently—every hour—with new data assimilation and forecasts. This rapid update cycle makes it ideal for short-term, real-time weather predictions, typically out to 18 hours (with some experimental runs extending to 48 hours).

Note

Currently Available Data

Hysplit: To run the sample data

Hysplit安装成功后，其实就已经包含了示例数据，它位于安装位置的子目录working里面，请检查是否含有这三个文件oct1618.BIN（该文件是ARL格式的气象数据）/sample_traj/sample_conc。其中sample_traj定义了模拟过程的起始位置。

Once HYSPLIT is successfully installed, it already includes sample data located in the working subdirectory of the installation folder. Please check whether the following three files are present: oct1618.BIN (which is meteorological data in ARL format), sample_traj, and sample_conc. The sample_traj file defines the starting location for the simulation.

Step 1 双击“Run Hysplit” Double-click “Run HYSPLIT”

看到如下图所示的GUI，含有Meteorology/Trajectory/Concentration/Advanced.

You will see a GUI as shown below, which includes the tabs: Meteorology, Trajectory, Concentration, and Advanced.

Step 2 单击Trajectory Click on Trajectory

单击Trajectory后，选择Quick Start和Run Example。它会依据预定义的sample_traj开始运行oct1618.BIN。

After clicking 'Trajectory', select 'Quick Start' and then 'Run Example'. It will run based on the predefined `sample_traj` using the `oct1618.BIN` file.

'starting time'等在此软件使用的都是UTC时间，注意与希望的时间进行换算。

In this software, terms like “starting time” are all based on UTC. Please remember to convert accordingly to your desired local time.

几乎瞬间会得到一个运行结果，如下所示，黑色的星号就是计算的起始位置。

The result will appear almost instantly, as shown below. The black asterisk indicates the starting location of the calculation.

这就是一个非常简易的利用自带数据的操作过程。

This is a very simple operation process using the built-in data.

Step 3 查验气象数据 Verify Meteorological Data

在Trajactory之下找到Setup Run，弹出如下所示的配置窗口。

Under ‘Trajectory’, find and click ‘Setup Run’, and a configuration window like the one shown below will pop up.

在Selected Files，已经列出了oct1618.BIN文件，如果没有列出该文件，请通过“Add Meteorology Files”添加该文件。

In ‘Selected Files’, the file ‘oct1618.BIN’ should already be listed. If it is not, please click ‘Add Meteorology Files’ to add it manually.

单击“Setup starting locations”，如下图，你就会看到初涉的起始点是同一位置的不同高度，当然可以被修改为不同的位置或者高度。

Click ‘Setup starting locations’ (as shown below), and you will see that the initial starting points are set to the same location at different altitudes. Of course, these can be modified to different locations or altitudes as needed.

Step 4 运行此配置 Run the Simulation

How to install HYSPLIT on Windows

在安装HYSPLIT之前，需要先安装Tcl/Tk和ImageMagick。

Before installing HYSPLIT, you need to install Tcl/Tk and ImageMagick first.

Tcl/Tk

打开Air Resources Laboratory - HYSPLIT Graphical Utilities，直接单击下图红框的链接，开始下载tcl.zip，下载后解压，并将整个文件夹放在你希望的地方，我一般放在C盘之下某个文件夹之下。

Open the "Air Resources Laboratory - HYSPLIT Graphical Utilities" page and click the link in the red box shown below to download tcl.zip. After downloading, extract the files and place the entire folder wherever you prefer — I usually place it in a subfolder under the C drive.

ImageMagick

继续在Air Resources Laboratory - HYSPLIT Graphical Utilities，单击下图红框的链接。

Still on the Air Resources Laboratory - HYSPLIT Graphical Utilities page, click the link in the red box shown below.

在新页面继续单击下方红框处的链接，选择最新版的软件。

On the new page, click the link in the red box again to select the latest version of the software.

在新打开的页面，找到Windows Binary Release之下，选择ImageMagick-XXXXXXX-dll.exe下载。

On the newly opened page, find the section titled Windows Binary Release, and select ImageMagick-XXXXXXX-dll.exe to download.

下载后，双击开始安装，安装在默认位置即可，当出现下图所示窗口时，务必选择两处，直至安装完毕。

After downloading, double-click the file to begin installation. Install it in the default location. When the window shown below appears, make sure to check both options before proceeding, and continue until the installation is complete.

HYSPLIT

参考Air Resources Laboratory - HYSPLIT Registration Instructions，该软件含有注册版本与非注册版本，注册版本仅多一个Forecast功能。一般，我们先安装非注册版本，注册版本根据需求来选择。打开HYSPLIT for Windows - Public (unregistered) Version Download，填写自己的邮箱即可开始下载。来到了下载列表，一般我选择最新版的.zip版本下载，解压后将其放在合适的位置即可使用。

According to the Air Resources Laboratory - HYSPLIT Registration Instructions, the software includes both a registered and an unregistered version. The registered version only provides one additional feature — Forecast.

Generally, we start by installing the unregistered version, and the registered version can be used as needed.

Go to the HYSPLIT for Windows - Public (unregistered) Version Download page, enter your email address to begin the download.

Once you reach the download list, it's recommended to download the latest .zip version. After downloading, extract the files and place them in a suitable location — the software is then ready to use.

Unzip the file and move the HYSPLIT folder and everything therein to the C: drive. The end result should have directories C:\HYSPLIT\exec, C:\HYSPLIT\working, and others. Then create the "Run Hysplit" shortcut on your desktop. To create the shortcut, open Windows Explorer and navigate to the C:\HYSPLIT\guicode directory. Right-click the hysplit.tcl file and then choose "Send To > Desktop (Create shortcut)." Rename the created shortcut to "Run Hysplit."

我们还需要另外一个路径，找到之前存放Tcl/Tk位置，找到其完整路径（XXXXXX\tcl\bin\wish86t.exe）并复制。

We also need another path: locate the folder where you previously saved Tcl/Tk, find the full path to wish86t.exe (e.g., `XXXXXX\tcl\bin\wish86t.exe`), and copy it.

回到刚刚在Desktop创建的"Run Hysplit"，右键找到Properties，在Target里面加入刚刚找到的路径，注意两个路径在一起，并有一个空格分开，最后单击OK完成。

Then, go back to the "Run Hysplit" shortcut you just created on your Desktop, right-click it and select Properties. In the Target field, add the path you just copied after the existing path. Make sure the two paths are separated by a space. Finally, click OK to save the changes.

双击"Run Hysplit"，就可以运行了。

Now, double-click "Run Hysplit" to launch the program.

Test the Installation with GUI

如图所示打开Contour Map，并在新窗口按照下图所示配置测试数据，最终单击“Run CONTOUR”。

As shown in the figure, open Contour Map, and in the new window, configure the test data as illustrated. Finally, click "Run CONTOUR".

如果返回如下图的结果，就表示安装成功了。

If you get a result like the one shown below, it means the installation was successful.

Matlab: Wind Rose

风速玫瑰图的制作参考“风向频率玫瑰图”，各风向的风速代表该方向的平均风速。风速玫瑰如下图。数据中0°表示静风，360°表示正北风。

The creation of the wind speed rose diagram follows the wind direction frequency rose diagram, where the wind speed for each direction represents the average wind speed in that direction. The wind speed rose diagram is shown below. In the dataset, 0° represents calm wind, while 360° indicates due north wind.

风向频率玫瑰图的制作参考“风向玫瑰图”，所不同的是这个玫瑰图有37个风向，分别是0:10:360，0°表示静风，360°是为正北风。测试数据的制图结果如下图，静风频率位于下图的中间，一个红边的圆形，例子中的这个静风频率太小了，所以看起来是一个红点。

The creation of the wind direction frequency rose diagram is based on the wind rose diagram, but with a key difference: this diagram includes 37 wind directions, ranging from 0° to 360° in 10° increments. In this dataset, 0° represents calm wind, while 360° indicates due north wind. The plotted results for the test data are shown below. The calm wind frequency is represented by a red-bordered circle in the center of the diagram. In this example, the calm wind frequency is very low, so it appears as a red dot.
